So my mp3 player charges throught the usb port and i guess i let it run completely run out of batteries, because now it isnt turning on or charging or anything, It registers as a drive in my computer but i cant edit my playlist because nothing shows up. I obught it used so maybe that is why they sold it, but i dont know why it wont work, and the RCA website doesnt have any trouble shooting sections for this model anymore. Please help me if you can!! thanks.
