TheChoroQ problem is my friends downloaded from the same fitgirl file and plutonium worked so idk what is wrong with me

HannesC I use 'Windows security'

so I downloaded the game from fitgirl repacks on torrent along with some of my friends, and they setup the game and plutonium and it all worked. However, for me, when I chose the directory that had the call of duty black ops 2 files in it, it did not work. Can somebody help?
