Razer Naga up/down movement bug!

Hello guys!
I have owned a Razer Naga for nearly two years now. And I have had several problems with it in the past, that I have managed to solve. (Or has solved it self..)

I remember having this bug once or twice before, but I have managed to solve it.
I cant remember how though, I just remember having this exact problem a few times before..

I can move the mouse cursor left and right without problems. But when I try to move the mouse up and down, it stops, and suddenly moves again. Like if the edge of invisible program window is blocking the mouse from moving for a second.

It is really hard to move the mouse, so everything takes a lot longer time. I play games a lot, (thats why I bought the Naga..) so it's really annoying to not be able to play, if there isn't any fix to this.

I read another thread about a guy who had the exact same issue, who had to get a new one. Because razer told him it was defective! So have I managed to use a defective mouse, for 2 years, managing to solve the problems each time?

Anyhow, I need help! And every answer is greatly appreciated!

Well, I resintalled all of my drivers. And uninstall Synapse.
I uninstalled the Naga from the device manager and repaired all of the drivers, and rebooted.
After repairing the drivers another time, it worked.

And I apparently have to repair my drivers on every start up to be able to move the mouse cursor.. ffs..

The cursor movement is still bugged, help would be apreciated..

I seriously need help!
