what should i do with my RCA mp3 player?

i was downloading a couple of songs one night and when i finished i playing it and i was happy, then the next morning i was excited and everything because i had some new songs to listen to but, i tried to turn on my mp3 player & it wouldn't turn on.so then i went to go charge it because i thought it lost its charge. so whenever i connect to the mp3 to the computer it would say that i need to connect it to the computer ,when i already didi! (i am so very sad)
