When I installed the patch v1.9, it shows black screen with audio in it, but no pictures shown on my display. And, I can barely see anything on my screen. Even though I have downloaded the latest NVIADIA driver 275.33, it doesn't work still. So, can anyone help solve this black screen issue.

I am currently using EVGA GeForce GTX 460 SSC 1GB GDDR5 Video Card.
