3D graphic mode problem.

Hi all, i've just come back from holidays and i started crossfire autopatch today wich started downloading updates. Once in game i've noticed a weird graphic, like the 3D one that you can see at the cinema when you go for a 3D film. I don't know how to fix it, in other words i don't know how to turn back to the standard graphic. Could someone help? Thanks all.

Edit: Problem solved, fixed it by pressing "ctrl+t" deactivating the NVIDIA 3D function.
