If you run it with the .exe file, add
debuglevel=62
to the jEmplode2.lax file (anywhere) This will turn on all but protocol-level debug messages.

If you run it with the jar file, run it instead from the commandline with:

java -Ddebuglevel=62 jemplode2.jar

Log the output from that, download the database from your player, then drag and drop and have it hang, then quit and send me the output log.
