Okay, so my mp3 wont let me do anything to it anymore. I am trying to add new music files to the device and it doesn't let me and I have no idea why. I'm still using the same computer, and nothing has changed. It doesn't make sense. I checked to see if my mp3 was full ( of music ) and its not, but then I also tried deleting all the files off the device and it wont let me do that either... Anybody got any advice!? I got a 68 hour bus ride coming up in 2 days lol... I need this fixed!
