My unit worked great for a few months… then I tried to update my songs, but it wouldn’t respond. I tried everything on the computer side of things, but still no luck. So I went on with life and continued to use it as it was. Then, I recently tried to recharge the unit and the screen lit up to show the connection and I could see the yellowish battery picture but the unit did not charge at all. I read all my paperwork for the device and tried to charge it again… I did notice that the battery symbol was not flashing…I don’t know if the problem is on my end or the compay’s.Any advice?
