"Wrong CD Key" on reinstallation attempt

["Wrong CD Key" on reinstallation attempt]

Thanks for your help, i will talk to my friend again. I just wonder how did the ArmA 2 key work but the ArmA 2 OA didn't.

There's your answer. If it was bought from our store why then go and ruin your purchase by using an illegal method to get our software? Makes no sense, are you sure he didn't just buy the CD Keys from somewhere else?

I'm sure, he got it (I think) from Arma X: Anniversary Edition. He bought 2 copies, one for him and one for me. I couldn't find where to download the game so i had to use the torrent one. The mail that he sent me didn't have the download link.

Hmm your friend bought the game but then gave you the CD Keys? Am I missing something here? That sounds a little fishy?

Big sorry, i meant he bought it for me. Could it be problem with the game version that I download ? It was a torrent version.

I have exactly the same problem as you. My friend purchased ArmA 2 CO from bistudio store and gave me 2 cdkeys for ArmA 2 and Arma 2 OA. The Arma 2 key was fine but when i install Operation Arrowhead, it said "Wrong CD Key". This is frustrating.
