I couldn't find anything in Documents & Settings. There was what looked like a database in the audio receiver directory in a folder "DB". I deleted that and same problem.

I did a search and the file is definitely gone from everywhere. It could be that that is not even the issue as I see the same error up above and it obviously recovered from that. I am attaching my log.

Couldn't figure out how to attach, so here is the end:
