Ive had that problem too,(until yesterday) and this is how i solved it: --------->Oh and btw, dont blame me if you screw up in the regedit, if you dont know what too do google for a guide.<---------------------------- 1. Uninstall arma 2 and/or arma free, operation arrowhead and battleeye! 2. Go into regedit and delete the folders with the cd-keys(But write them up if something goes wrong...) i deleted the whole bohemia interactive folder(also i had 2 for some reason) 3. install arma 2, and launch it. 4. Install operation arrowhead, and launch it. 5. install the latest beta patch. 6. Get six launcher and let it download DayZ for you. And that should solve your problems if you do it in the RIGHT ORDER, thats important! :) --------->Oh and btw, dont blame me if you screw up in the regedit, if you dont know what too do google for a guide.<---------------------------- Good luck!
