redsn0w won't reconize iphone 3gs in dfu mode for Just Boot

[androidalais]

I had to reboot the device after installing winterboard from the cydia store and now redsn0w 0.9.15b3 will not reconize it when it's in dfu mode when i try to use the Just boot application. any ideas?

It could be a problem with the Apple device drivers. Easiest alternative is to try another PC.
