Im getting the error 1b problem as well, I am using a regular CnC Generals Zero Hour, English, and am running windows 7 32 bit, and no other mods have been installed. The regular CnC works fine and the only thing I have done to my game is get a no cd exe (also its a legit copy of CnC, my little brother plays this game and he uses mods, We have TFD also but that seems to be a problem with mods so we just install regular twice and use different cd keys). Please help
