sansa fuze 8gb problem

i get a sansa fuze today and i try to download some songs.  after a while it says usb fried or something and i cant turn on my fuze!  can i fix this?

What is the exact message that you’re seeing and where is it being displayed? Is it on the player that you see this or the computer?

Hi, im having issue converting, i have the 8gb sansa fuze, and i have a file in avi format that i put into the converter and waited 2+ hours and i didnt see a single % increase, it stayed at 0, its a 20 min video, any ideas on how to get this to work?
