if it was a installer should have had a option to check apply crack if not should have been a codex or other type folder with crack files inside it you place in game main data folder
ok look in the folders it should be one named propet or codex or juct crack etc and contain some files usually 2-4 called steam.api etc that go into your main games data folder
I work in this game.
