I downloaded Call Of Duty Black Ops as a torrent on piratebay about 4.23 GB in size only for me to discover on launching the "setup.exe" file, It wasn't in English. I kinda got tensed and confused cause of the time and amount of bandwidth downloading the game cost me. So I was hoping I could get some help with a way to change the setup language of the game. I'll really appreciate help as soon as possible. Regards.
