Hi! I have had this mp3 player for a while, but it just now started to give me problems. It is an audiovox smp3-330-128s. When I erased my old songs and added new ones, the names of the new songs registered into the player, but the songs do not play. The screen simply flashes the number and title of the song and then goes on to the next one. I don't know what I'm doing wrong! Any help would be very appreciated.

Nancy
