Sys_CriticalMessage: Main windows is not available.

Hi I've got a problem - cannot start Doomsday Engine with "connected" Plutonia IWAD. There is no other pk3 and WADs with additional textures and music, just one standard WAD with Plutonia levels (i've tried to play Doom 2 with DOOM2.WAD - same sad story). After "Play" button I see 3 messages with "Sys_CriticalMessage: Main windows is not available." and after this errors I see the last message "Error creating main window". I really don't know what to do... I thought that it can be because I haven't PhysiX, but today I installed this thing and got same result. Starting with XP SP 3 compatibility mode doesn't give anything, starting with administrative rights - same sad story, tried to start without Windows Aero - same... UAC is off, I added Doomsday's folder to KIS 2011 exceptions, but it doesn't work. Other games works properly... What's the hell is going?

My computer's configuration:
Windows 7 x64 Ultimate
NVIDIA 8600 GTS 256 Mb
AMD Athlon X4
3 Gb RAM

By the way, I installed Windows 7 x64 just 3 days ago. I know, that my card is not so strong, but in Windows XP SP3 x86 it worked properly (with many additional packages)...

Sorry for my bad English. Thanks in advance

Haha, problem is solved xD And there is very stupid solution: update video-drivers to latest version "Native" drivers from Windows 7 driverspack for my videocard don't worked properly with games which uses OpenGL, at the same time latest drivers from nVidia site working amazing. Thanks anyway xD
