I've had the same problem a while back, as I remember reinstalling the application fixed this problem, but now I am having another issue with this software, I don't think that when I change any setting in this software it actually gets changed! I tried so many AA and AF settings, and whenever I set the AA for 2x for example from 4x, I go to the CP and find it still 4x, same happens with AF, so I don't know if the same problem goes with the other options, if that's true then using this software is pointless for me! Anyone knows how to fix this problem too?
p.s: isn't this supposed to be in the "Software" forum?
