i have the same specs i dont think it has to do with your computer friend, im not certain it will work if you're using a cracked version.
Really the only things you have to do are
2. replace common.ff
if that doesnt work let me know
Hello Harold, I've been trying to get this to work for a while on default maps and modded. Neither work. Neither on single player, or co-op zombies. When I say single player I mean single-player zombies. I have done exactly as you said and it won't work.
Hello harold. I've done what you've said to install it. Replacing the common.ff then I launch my game in any map, including default maps. When I hit Ctrl+F, F+Ctrl, RightCtrl+F, F+RightCtrl nothing works.
