>invalid fid type in "/drive0/fids/2071": ""

Oh, Good! The error messages *work*!

Go back to your player, and view this file:

http://your.player/drive0/fids/2071


Tell us what you see.. I'm betting either (1) nothing,
or (2) no line that looks like "type=tune" or "type=playlist".

All of those are signs of a "bad database" on your player.

Cheers
