I have the same exact problem, but I have the 1GB version and I’m using Windows Vista. Same exact error message and all. When I try to connect to the computer it shows a graphic of the mp3 player and the computer connected by some weird blob (looks like static and it’s in the shape of a square). When the device isn’t connected to the computer and I try to turn it on, I get the SanDisk logo and then nothing. I hope someone can help.
