Zen V Is Totally Dead!

My Creative Zen V worked very well for a good 3 months, but I'm really upset because it doesn't show any signs of working again! All I remember doing is leaving it on my bed. I might have left it on, and that might be why it went dead, but the problem is, not even the usually blue lights are flashing. The computer doesn't recognize it, and the screen is completely black. There's no possibility of getting a refund I don't think, so I'm very upset.
