Omg im really pissed. number 1, i have downloaded arma 2 free from your website not steam and it works fine. but opperation arrowhead i got from steam. it worked fine at first but i deleted it because i had to get ready to ship my computer. there was a delay so i got back on my computer and reinstalled it. but now when i run it, itll get to the bohemia interactive logo and crash sayin "Error: bad serial given in setup". i have tried practically everything and nothing fixes it. i want you to tell me what to do to fix it because i paid for this d*** game.
