Black screen after opening

[Nagasaki]

My single player works fine, no issues. But multiplayer will open to a black screen with just my mouse cursor on the screen.

All this started when MW2 would not find any matches so i uninstalled MW2 and re-installed the game to see if it would fix that but instead i get a blank screen.

I have spent days looking on Google for a solution with no luck this far.

All my drivers etc are up-to-date.

My system specs are:

AMD Phenom II X6 1090T
8GB OCZ DDR3 1600
ATI 6970 2GB GDDR5
Asus Crosshair IV Formula

I hope someone can help me out here.

Thanks
