Hi,
I have just recently bought Arma2:Combined Operation on Steam. Having previously owned a seperate copy of Arma2, I decided to give that to my friend.
Since internet cap comes in a premium in our country, re-downloading the contents just to reinstall is out of question!
I need a way to reset the game so that I can input my steam key into it, because all I did was copy my old Arma2 files into my steam folder.
Thanks in advance!
