Okay, so my older brother got this huge collection of PC games off one of his friends, all pirated, all pre-installed (as in, the folder directly taken from the C drive) All of them were cracked so you don't need a CD, but when I try to load up Call of Juarez (the first one) It's gets a serial key error. I want to know if It's possible to reset a game's CD Key even after the installation. I DON'T NEED A CD KEY! I FOUND ONE ON ANOTHER WAREZ SITE WHICH APPARENTLY WORKS. Also, if this is against the rules, just alert me and then close this topic. Thanks!
