Cant move mouse

Hi mates!

can someone help me ?

First try Cutting + Pasting your WTF folder to your desktop (akin to deleting it, but this way you at least can restore your WTF folder back as it contains all your settings, macros, and addon settings.)

If that doesn't work try updating your graphics drivers

If not, then you may need to reinstall.
