Need help! I have a Creative MuVo TX USB 2.0 which worked wonderfully well except one day, I used it for while jogging and then all the controls got messed up. The on/off button no longer works. Pressing the scroll and volume buttons turns it on/off. When plugging it in my PC it is not recognized as a "Removable Directory". Is there some sort of "reset" button that can bring everything back to its default setting? Please help. I would hate to part ways with this really neat MP3 player.
