I've got that.
I have installed NO mods at all. Just a vanilla version of Skyrim from STEAM.
It was working brilliantly until today. When I went on for the first time in about a week.
It asked to download AMD CC 12.2 (I was previously on 11 or something) and now it looks like that.
Shame really, because I doubt I will play it again now. Have a lot of hours invested, but its the kind of thing that stops me playing and I'll loose interest.
I searched the internet for the last 30 minutes on how to go back to the old version of CC, but cannot find an easy way.
