I cant run any mods! I've got the Half Life generation ultimate edition with Counter Strike and Opposing Force - I've installed Half Life, everything works, but when I try to play any mod, it loads up and just before the mod actually plays, an error comes up saying "cant open valve/fonts.wad" - I searched my entire HD for this file and it's just not there. It's not even on the CD, and reinstalling didnt make it appear either.
What's up?!
