T2 Crashes to desktop...

Recently, whenever I try to load T2, it changes gamma and everything, the screen goes black for a second (as if loading) and then it crashes back to desktop.

I believe it started happening after I used http://housecall.trendmicro.com

I tried reinstalling, I tried changing my drivers, and I tried deleting .dso's

Help please

Also, I get an error when trying to load Steam as well (for counterstrike)

I got steam to working by deleting all folders etc. in the steam folder, and then running it, so it re-updates itself. However, I reinstalled T2 and it still does this
