I just bought a new 8g mp3 player on Ebay. It came with a teenytiny manual, but no instructions--I'm a novice at this!-on how to turn it on and off. It charges, but once unhooked from charger, nothing. I'm hoping someone else has a generic thing like this with at least a picture of how to use it. Also hoping the seller will help. Any suggestions? thanks and Merry Christmas!
