i just bought the game and i can't seem to get it to install, i bought the arma 2 combined operations and when it asks for an installation key, i put it in but it says wrong key. i put in lower case letters and capital letters but still the same problem. what am i doing wrong? ---------- Post added at 11:14 PM ---------- Previous post was at 10:58 PM ---------- nvm. i think i figured it out, 2 different manuals with 2 different codes. i was stupid enough not to notice this. i figured 1 manual, 1 code but didn't notice the other manual with a code on its back.
