Hey there.
I recently decided to try my Roccat Kone on my laptop with Windows 7, to see if it'd work. It's quite new for me, but, to my surprise, the mouse worked excellent after simply inserting it and installing the driver.
I then played some CS: S for about an hour, when I quit it and did something else. Suddenly, out of nowhere, the mouse didn't respond to my movement.
I could still left click, right click, etc, but it didn't react to being moved. It was as if the lazer tracker had been turned off.
So, I tried uninstalling the driver, reinstalling, blocking the Windows 7 automatic retrieval, etc, updated drivers, etc.
As of right now, my problem is the same as it was in the beginning. The cursor won't move. Except for that, everything works.
(Yes, it won't move for that mouse. Other mice work just fine.)
Any help, advice or anything would be greatly appreciated. I'm a bit lost as I don't understand why it worked at all in the beginning. Almost sounding like it is a hardware failure.
I intend to try it on a different computer, to see if the result will be different. Until then, I want to see if there are any other things I can try.
