Wednesday, December 5, 2012 the in-game FEAR server list stopped working. To fix this, we released a patch that fixes all the problems this caused.
If you can’t use your new cd-key, it is likely because you do not have the latest game patch.
Before releasing the patch, the alternate way to change your cd-key was using the FEAR Launcher.
Download and use the FEAR Launcher 1.4
