I reinstalled 2.00 to get rid of hijack and everything worked perfectly fine again. Then I downloaded a new hijack file incase my old one was corrupt, and reinstalled it. Same problem again.

I think I am currently fighting with the same bug. Something is creating new style FID directories (/empeg/fids0/_00000) on a player using the old fid structure. Once those directories exist jemplode (not sure about emplode) will start using them on the next sync and you will lose access to any previously uploaded music.

I am guessing this is related to the fid rewriting code added around hijack 344 so if you have an older copy you might try downgrading. Perhaps the player software is getting confused by the fid rewriting and trying to be helpful by creating the directories?
