nvm mind i fixed it by using vid restart command on dev console

Xerxes could you show me an image of where to do this? im very confused

Xerxes what kind of clean files? i'm not quite tech savvy with this

Whenever I load up MW3 it wont let me hover my mouse to a selection and the only button that works is the dev console and esc. Is there a fix to this, if so please tell me so I can fix it and play.
