I erased all the playlists in emplode (1.02, right? ...

I don't know what version of the software you're running on the player, so it's worth it to point out that the emplode version should match the player software version. I don't know what would happen if they were different, honestly.

Also, if that's right (you should upgrade to 1.03, probably, if not 2.00beta13, but that's beside the point), check to see if you have unreferenced files. It seems like there was a specific check for that built into the 1.0x software, but I don't remember now what it was, so look around for it. If something's there, then you've deleted all the references for those files, but not the files themselves. Try deleting them again.
