Error "[program name] has been blocked from accessing Graphics hardware" After 8.1 update

This only seems to happen with games and my Zune app. I have tried editing the regedit, reinstalling games/AMD drivers, and disabling all security programs and features to run games. I have had absolutely no luck with it. I have also tried reaching out to some of the games I play communities and no one has been able to help me. Is there anything else that anyone can suggest to me to try?

The games Ive installed are up to date and I updated. I also updated from windows 8 64bit. I have tried the microsoft and other game communities. For some reason games that were pre 8.1 have this problem while new installs dont.

-8 gigs ram
-i5 ivy bridge
-7950 XFX DD Video card
-Windows 8.1 64 bit
