fuze wont sync playlists

my sansa fuze has been working fine with windows media player for ages.

i then decided to try out Song Bird which when i synced my fuse wiped all my playlists. i tryed to sync new playlists. i have tryed songbird, mediamonkey and also wmp. all go through the sync process and add music files to the sansa but the playlists are not in the playlist menu.

i have tryed using the msc and mtp settings, re formatting, and down and upgrading the firmware and nothing seems to work. i have scoured the forums and tryed various sugestions with no positive results.

can someone please help me
