GaabrielSolza 0 Posted June 29, 2014 (edited) I bought Arma 2 Combined Operations while ago, after it installed Arma 2 and Arma 2 OA, right after downloaded and installed dayz commander. Soon after I updated within ARMA 2 dayz commander but when I clicked to install a message appeared saying: Wrong CD Key, and completed the installation. And whenever I go into servers can not always say Wrong CD Key Edited June 29, 2014 by GaabrielSolza Share this post Link to post Share on other sites
