Windows 7: Catalyst messed with my screen settings.

Help!
I was updating my AMD Catalyst driver, (from 1.xx~ to 2.xx~ is the least I can recall)
When I got a BSOD. All restarted correctly, and the installation still succeeded, but my PC's data knowledge about the graphic card is wiped. If I try to start CCC I get the error; "There's no graphic driver for the AMD-graphic card installed, or the driver doesn't work. Please install the AMD-driver on the hardware it belongs." Which I did. The second screen now works as a identical one, instead of its original function, as extra desktop space. Do you guys know why CCC messed with my screen settings?

Thanks,
Sauze.

EDIT;
Nevermind! I first reinstalled the *stable* version, which didn't help.
But to some reason when I installed the "Unstable" BETA version, it worked.
PC is a strange thing.
