AL-Marlon 0 Posted June 23, 2012 Hi, I think I have searched enough but still couldn't find how to solve these problems:1. Addon 'Takistan' requires addon 'CA_E'.2. When I click the OK button, the Day Z screen opens.3. The screen closes and gives this "Bad serial number given in setup" error.I have tried the solutions I have found on the other threads for the "Bad serial..." but none of them worked for me.Any help would be appreciated. Thanks!P.S.I can play both Arma 2 and Arma 2 OA. Share this post Link to post Share on other sites
