fuze is super hot and frozen, help

I connected the fuze to the computer like I always have. Windows Media Player doesn’t recognize it and the graphic with four little different colored swirls come on and now it is super hot. Have held the power button down several times, but it just won’t clear, turn off or change course what so ever. Wtheck? Anyone have this experience?

Unplug it, let it cool down and call Tech Support, something is really wrong.
