Ok, I've said it a few times, and each time it's come up good..

open a terminal and type:
cd .rtcom-eventlogger
mkdir keep
mv el.db* keep

Pay very close attention to the spaces and symbols.. its all lower case..

After that, turn the phone off, then back on..

Not sure what causes this, but either way, we've backed up the broken data base incase a) this doesn't fix the problem and b) I get round to doing more in depth debug (in which case I might ask you for a copy.. don't worry, its painless
