evanisdashizz 0 Posted January 5, 2013 I need help starting the mod. I downloaded Arma II and the expansion pack for it and then I downloaded dayzcommander and I clicked on some threads to try and start playing but it won't let me load the game. It keeps coming up with a message that says: "bad serial number given in setup" What do I do?!? Share this post Link to post Share on other sites
Rage VG 4033 Posted January 5, 2013 You need to go into your Steam Library and play both ARMA II and ARMA II: Operation Arrowhead at least once. You just have to load up to the main menu. Share this post Link to post Share on other sites

evanisdashizz 0 Posted January 5, 2013 Something is wrong with it. it says Operation Arrowhead has a bad serial number too. Maybe the one I bought and downloaded is broken or something? Share this post Link to post Share on other sites

finkone 320 Posted January 5, 2013 If that don't work... try to restart. Windows can be a whore at adding registrys sometimes. Share this post Link to post Share on other sites
