i've tried everything.

No matter what i try i can't get crossfire to work. The closest i have come is it making it to the image saying please wait or something like that, then it doesnt respond. I have reinstalled it, restarted computer, changed resolution, and also updated my graphics card driver (which screwed up my resolution - now i have a black border around my screen. I have a AMD Radeon 6570 2gb dedicated graphics, 27" benq monitor. How can i fix this? ( also the black border problem if you can help there)
