FATAL ERROR: Unable to initialize display! No matching GL pixel format available

[aridez]

Have you always tried to run the game in 1024*768 resolution in fullscreen? It sounds like it tries to set a resolution for the screen that is not supported. Have you tried other resolutions or to run the game in window mode to see if that changes anything?

I've tried many other resolutions and none works, this was the last one I tried, I usually run it at 1280x1024, and it worked before the patch.

edit: I also tried the window mode and didn't work.
