I changed the prp file and tried again. I fear it didn't help. Here is the output
from commsql and the prp file

!---------------------------------------------------------------------
!
! BASIC PROPERTIES
!
!---------------------------------------------------------------------

!
! Path where index tables are held. Can be absolute or relative
! to the properties file. Defaults to tablePath.
!
indexPath=./indexes
!
! Path where system tables are held. Can be absolute or relative to
! the properties file. Defaults to tablePath.
!
systemPath=./system
!
! Path where database tables are held. Can be absolute or relative
! to the properties file. Defaults to "current" directory.
!
tablePath=./tables
!
! Path where results set tables are held. Can be absolute or relative
! to the properties file. Defaults to tablePath.
!
tmpPath=./tmp
!
! Non-zero means paths are relative to the properties file.
! Default is absolute paths for files.
!
relativeToProperties=1
!
! Alternative partitions can be defined so that tables can be placed
! in multiple locations. Each partition is numbered: 1, 2, 3,... Tables
! can be created on partitions using the syntax
!
!   CREATE TABLE <name> ON PARTITION <number>...
!
! The partition count has to be supplied.
!
!partitionCount=2
!
! The locations of each partition must be supplied. These are always
! absolute path names.
!
!partition1=d:/petes
!partition2=c:/temp


!---------------------------------------------------------------------
!
! TUNING PROPERTIES
!
!---------------------------------------------------------------------

!
! The amount of each column to cache, expressed either as an absolute
! number of rows or as a percentage figure. Defaults to 256 or 10 respectively.
!
cacheAmount=512
!
! CACHE_ROWS Must be one of CACHE_ROWS or CACHE_PERCENT. Determines whether
! to cache columns in tables based on an absolute number of rows, or the
! percentage number of rows in the table.
!
cacheCondition=CACHE_ROWS
!
! The percentage cache hit improvement required in order to move the
! cache to a new location in a column.
!
! (Currently not implemented).
!
cacheResetPercent=10
!
! Non-zero means that database changes do not get written to the
! database immediately. See tuning.html.
!
fastUpdate=0
!
! Percentage of free space in an index that must be present before
! the index reorganises itself. High values means frequent index
! reorganisation. Low values means slow index inserts.
!
indexLoad=5
!
! The number of cache misses to include in calculations of the next
! base for the cache.
!
! (Currently not implemented).
!
missesInCacheStats=100
!
! Non-zero means that results sets get instantiated on disk. By default
! InstantDB holds results sets emtirely in memory (apart from Binary
! columns). For large resulst sets this can be a problem. This property
! forces all results sets to be held on disk.
!
resultsOnDisk=0
!
! Similar to cacheCondition but applies only to disk based
! results sets. Default is CACHE_ROWS.
!
resultsSetCache=CACHE_ROWS
!
! Similar to cacheAmount but applies only to disk based
! results sets. Default is 100.
!
resultsSetCacheAmount=100
!
! Number of rows to read into the disk look ahead buffer.
! Recommended to be set somewhere around 128 to 256.
! Default is 20.
!
rowCacheSize=128
!
! By default, InstantDB only does a cursory search for deleted rows during
! UPDATE statements. Setting searchDeletes=1 causes more detailed searches
! for deleted rows. This slows down UPDATE executions, but reults in more
! compact tables.  Default is 0.
!
searchDeletes=0
!
! The interval, in milliseconds, between checks for statement execution
! timeouts. Default is 5000.
!
!timerCheck=5000

!---------------------------------------------------------------------
!
! LOGGING AND DEBUGGING PROPERTIES
!
!---------------------------------------------------------------------

!
! Non-zero means include SQL statements in the export file.
!
exportSQL=0
!
! Non-zero means trace output also directed to console.
! Defaults to 0.
!
traceConsole=1
!
! Relative or absolute path where exporting and tracing goes.
!
traceFile=./trace.log
!
! Bitmap of various items that can be traced. See debug.html.
! Defaults to 0.
!
traceLevel=2

!---------------------------------------------------------------------
!
! TRANSACTION AND RECOVERY PROPERTIES
!
!---------------------------------------------------------------------

!
! 0 means do not perform recovery on startup.
! 1 means perform automatic recovery
! 2 (default) means prompt the user using standard in
!
recoveryPolicy=2
!
! Sets the level of transaction journalling. See trans.html.
! Defaults to 1.
!
! 0 - No journalling takes place.
! 1 - Normal journalling (default).
! 2 - Full journalling.
!
transLevel=1
!
! When doing an import, defines the number of rows imported
! before the transaction is committed. Recommended value 8192.
! defaults to 100.
!
transImports=100

!---------------------------------------------------------------------
!
! DATE, TIME AND CURRENCY PROPERTIES
!
!---------------------------------------------------------------------

!
! Number of digits after decimal point in currency outputs. Defaults to 2.
!
currencyDecimal=2
!
! Currency symbol used in currency outputs. Defaults to $.
!
currencySymbol=$
!
! Default format for date columns. Defaults to "yyyy-mm-dd".
!
dateFormat="yyyy-mm-dd"
!
! If set, then all two digit dates less than its value are interpreted
! as 21st century dates.
!
!milleniumBoundary=50
!
! Set to 1 causes the date string "now" to store a full timestamp.
! Default is to store only the date for fields with now hour in the
! format string.
!
nowMeansTime=0

!---------------------------------------------------------------------
!
! STRING HANDLING PROPERTIES
!
!---------------------------------------------------------------------

!
! If set to 1 then String hashes use the JDK Object.hashCode() function.
! By default, uses InstantDB's String hashing.
!
altStringHashing=0
!
! Set to 1 to cause LIKE clauses to always perform case insensitive
! comparisons.
!
likeIgnoreCase=0
!
! Same as SET LITERAL STRICT_ON. Prevents string literals being interpreted
! as column names or numbers. Default is 0.
!
strictLiterals=1
!
! Set this value to 1 (one) if you would like PreparedStatement.setString()
! to ignore "\" (backslash) characters when proceesing string constants.
! When set, InstantDB will not attempt to interpret \ as the start of an
! escape sequence. Default is 0.
!
!prepareIgnoresEscapes=1

!---------------------------------------------------------------------
!
! MISCELLANEOUS PROPERTIES
!
!---------------------------------------------------------------------

!
! Allows selected InstantDB keywords to be un-reserved.
! e.g. ignoreKeywords=url,quote would allow the keywords
! url and quote to be used as table or column names.
!
! This faciliy is provided for compatatbility reasons only.
! It's use is not recommended AND IS NOT SUPPORTED.
!
!ignoreKeywords
!
! Non-zero means database is opened in read only mode.
!
readOnly=0
