Update:
I have Half Life 1, Half Life 2, Half Life 2: Episode 1 and Half Life 2: Episode 2. Installed a bunch of mods such as Nightmare House 1 & 2, They Hunger, Afraid of Monsters, Paranoia, Dear Easther... Everything works except Cry of Fear.
Tomorrow i'll try to update my Half Life's gcf files, maybe i have an old version. I'll post here if it works!
