as I stated in the headline my screen gets black after I've entered into game (with both tutorial and a real match).

I can login normally though.

Mine computer statistics are following:

Windows Vista 32bit with
NVIDIA GeForce 8500GT
HP w19 Wide LCD Monitor
AMD Athlom(tm) 64 X2 Dual Core Processor

Mine NVIDIA graphic card driver is up-to-date (downloaded one today that was said to be latest in their website).

While the screen is black I can see white box moving where reads "INPUT NOT SUPPORTED".

As I looked up earlier posts someone had said that dropping the screen settings to 60Hz would help. Didn't for me. I also tried to lower size of the screen.
