Okay so it took me about 2 weeks to download Arma 2:OA. Little did i realized that you needed the original Arma 2 game as well (I bought OA first cause it was cheaper), so i bought the original Arma 2. After about another 2 weeks of downloading, my internet connection sucks, i finally got it started. So the point of this is because everytime i try to join a game, it says "Bad CD Key - Contact customer service" and i'm like wtf? you know, i want to play this. that's why i bought the game in the first place. So please anyone, help me out? Thanks.
