I searched the forums and everyone seems to have the problem cant join a game well here is my problem. Just knocked the dust off my arma 2 cd case and was going to reinstall game havent played it in forever my friend told me about this day z mod. I have my original owner's manual with cd installation key on the back. I put the cd in start the installation and it asks me to type the cd key in. When i type it in it says wrong cd key, I have never given my key to anyone else. I used to play the game alot about 2 years ago and the cd key worked fine.
