My problem is that i can play knight online only in window mode.
I have tried in full screen mode with different resolutions and settings (with and w/o sound, shadows etc) but it always ends me having and black screen(right after i start the game from launcher) and nothing happens so i have to boot my PC.
same problem with all the private servers (3) i have tried recently.
OS Windows 8.1 Pro
this problem might have aroused when i patched win 8 to 8.1 but not sure about it cuz i didnt play ko at the time.
any help is appreciated!
