I got counter strike source a couple of months ago. Once I got it I played it for three months, than got a new computer and uninstalled it out of my old computer and installed it in my new once. Once I installed it I realized that I threw out my instruction paper which includes my authecation code. So now I can't get my counter strike source to work without the code. So any ideas how to get a code can I buy it? Or any sites to get free codes or you can give me a code if you quit it. Thank you for any help.
