Hello
I've got a serious problem with L4D2. Whenever I load a campaign, or any game mode for that matter, the game quits when it is finished loading. The Mac Os X menu bar shows up on top of the loading screen and the game just quits. No error messages or nothing. It startet when the 19th of january update of steam came along. I could for a while, mend the game by replacing the steam folder from a previous one from time machine, but that is no longer possible with the 23rd of january update. Has anyone else experienced these problems?
UPDATE: Never mind, I have fixed it. Turned out there was a corrupt file and now the game is working again. For now... :P
