when I go to sync new music files it runs and says it is 100% complete. I disconnect and then when I try to locate them on my MP3 it says "List Empty". It has all the playlists listed I have ever synced but under the playlist it says "List Empty". I go back to try to sync them into the MP3 again, it says its already on the device. So where the hell is it then? I have been messing with this thing for hours, they just disappeared this morning when I uploaded a new playlist. I've done nothing different. Please help.....SOON!
