2 years ago i bought this mp3 player at Family Dollar. it was a 2gb GPX brand mp3 player. red and square. i had no problem with it untill recently. i didn't disconnect it from the computer when my computer just shut off. (it needed a cooling fan and i got that prob fixed) i was in the middle of renaming and moving my music to the proper names and folders. now it reads as a blank audio player, but my music is still there cause i can disconnect it from my computer (or any computer, does this to any computer i connect it to). any way i can fix this without deleting anything from my mp3 player?
