Curtis MP3 mp1004 - songs are on mp3 but won't play?

I've got 43 songs on my curtis mp3 but nothing will play. I've run through all the options and can't see any reason why it's not playing. New battery is installed. When I plug it into the USB port - all my songs come up in Rhapsody as listed as being in the player. There is an icon in the upper left hand corner - I don't know what it is and reading through the manual and user guide - I find nothing that matches it. It looks like it starts to play a song for about 3 seconds and then stops. Any idea what is going on here?
