I went to check dxdiag, and as it was loading, this message popped up that read - "DxDiag has detected that there may have been a problem accessing DirectShow the last time this program was used. Would you like to bypass DirectShow this time?" If I select yes, then it loads normally. If I select no, then dxdiag freezes up. I think that this might have something to do with a problem I am having in a game, Vampire Bloodlines. I have DX9.0c installed, and I can't uninstall it or reinstall it. I also have Catalyst 4.11 drivers installed for my X800 XT, which I already reinstalled twice. Any ideas?
