I have a Sylvania smpk8099 mp3 player which has worked wonderfully up until recently. Just today it started having trouble staying on. If I click through a menu too fast, it shuts off and the whole thing resets. The files are still there, but all the settings are reset. I really need to get it up and working by Wednesday; I have a college radio show and all the music I play is on this player. How can I return it to factory settings or at least get it to stay on?
