Thanks for the advices guys. The only thing is, he's one of my good friends on the floor. But, I'm still mad that he would take it without telling me. I saw him trying to make up random numbers where you put in the serial number for the game and it made me laugh. He's computer illiterate and I told him that he has a better chance being hit by a lighting bolt than randomly typing in a code. Than to my surprise when I stepped out of my room, he must have taken my cd. Im not that mad as in that I will not be able to play when he logs onto CS, but that he did it decievingly. Shame on him. Oh, by the way I did tell him to uninstall the game, but I doubt that will happen.
