So... I got a Roccat Kova free as a prize, I'm trying to use it, but having some problems!

Once I plug it in, it works for around 2 seconds, before finalising installation and then it dies (no mouse movement, lights dont change). Doesn't matter what port, when I plug it in, or anything. I've tried the Roccat Support page which gives me one answer, to move the mousewheel, and that doesn't work!

It randomly worked one time for about 40 minutes, till I rebooted.
