If GCFScape is installed, I can't play Left 4 Dead 2. If I try to launch the game, in the main menu it says the game wants to associate with .vpk files, but I can't click anywhere! The only thing I can do is ALT+F4 or CTRL+ALT+DEL. But if I delete GCFScape, L4D2 works good again.
How can I fix this? Why can't I click anywhere? Please help!
