This is my guess. I really have never heard of the player but from the description of your problem it sounds like you need to change the format of your music. Do you have a manual? If so look and see what type of music formats it accepts. It probly will accept .mp3 I would download windows media player 10. And rip your music in there and try to sync it to your device. If this doesnt help lmk I will try and help.
