I've been searching around the net for similar situations, but no one seems to have come across the following: as soon as I installed F.E.A.R. 2 and tried to launch it, the screen blacks out and there's a loud "ding" (Windows alert) in the background. I minimise the window, only to find the following message: Unknown Error The game client has failed to initialize. There have been others that have had this problem with F.E.A.R. 1 and it's expansions, but after following their solutions (e.g. enabling only one mouse/keyboard profile in the Control Panel, re-installing with a clean registry, etc.) the problem is still there. Right now I have a very expensive frisby D: Gurus, have any of you come across this problem (or better yet the solution)? EDIT: I've tried adding an exception in Windows Firewall for F.E.A.R. 2, but the same problem occurs.
