TBH, I'm finding the CC beta a little lacking. I haven't touched it for a week or so now. And in all honesty, I'm probably gonna uninstall it this weekend. Just not my type of game.
Anywho, with it not pulling up any DirectX info, there is most definitely a problem.
You said you uninstalled and reinstalled drivers? Are you sure they installed all the way, or properly?
Was the graphics card really dusty before you cleaned it? Are you able to check temps on your GPU?
Did you install any new software/hardware before this started happening?
