RTCW & Windows 7

Somebody with the solution to make function RTCW under Windows 7 x64 ? I am always made kick for Unknown Windows API etc…
I tested in mod compatibility and to start as an administrator and that still does not function

I play just on non PB servers as there is no workaround in the moment ....
Tried loads of tips ... but nothing worked.

If it is a problem with Punkbuster, than would the single player portion work fine?

the single player portion work fine?

Yes

On my System RTCW Singleplayer doen't work. After the starting console the screen turns black and nothing happens anymore. I can't get back to desktop or task manager - the system doesn't react at all.

It's the same with other Quake3-Engine Games like Star Trek Voyager or Fakk 2.

Does anyone have a solution?

Just found a fix for singleplayer:

Install nHancer, open RtCW profile while the game is not running, go to Compatibility -> OpenGL, check "Driver extesion limit" and type the value 4844.
