Last day I played Counter Strike: Source a lot without any problems. I was using: "-windowed -novid -w 800" in launch options.
Today when I wanted to play, I wrote the exactely same thing and when the game window popped up got a runtime error.
I tried to reinstall the game and it worked fine. But when i went in and out of the game the exact same problem appeared.
What can I do? I dont want to reinstall the game everytime i wanna play because it takes like 2-3 hours to patch the game!
