I think its working now. I uninstalled the mouse, restarted the pc (mouse worked). Then it said "you have changed your hardware settigs" or something like that. "you must reactivate windows".
Don't no why, but I done that fine.
Then it seemed to be working.
I'll restart the pc once more and tell you if its working.
Edit: Ok, I restarted my pc and the mouse doesn't work, lol. It's not working at the moment but I still managed to edit this post
I'll just restart my pc again.
Edit: It hasn't changed. Still not working when I restart my pc.
