Do you have "Hold" on ?
if not try connecting it to a pc, see if your pc recognizes it and then try again.

This mp3 doesn't charge your battery.
Try using a standard alkaline battery to power it

I would try downloading the latest driver, or reformatting the unit. If you haven't downloaded anything, you essentially have nothing to lose, so to speak!

Held the play pause button while plugging in the player to computer so computer will recognize the player even though it isn't on. Downloaded and updated the player off RCA site, which whiped out the memory but now it works at least, took about 10 min completely.
Completely charged it and it is working fine.
