dirt 3 issues with xfire

Hey ! i am having a issue with dirt3, it was working fine until today, i minimized the game, it took a crap. When i ran the game.exe again it was in windowed mode and is only using one video card! the came config file is set to Fullscreen=true and alt enter says normal window and i have tried full window, still runs windowed with 1 gpu. I had similar issues with dirt2 that didn't get solved.....
any one have a solution ?

Tried alt+enter ?

Yes, i have tried changing it from Normal window to maximized, same issue.

Edit:: I got it to run with both cards with some help of Radeon Pro, but still stuck in window mode.
