Okay, so, I started the Breaking Point launcher and pressed Update. Halfway through the update, it closed down for some reason. (I know BP is not an "official" mod, but I haven't had problems until now.) Since then, I've been unable to get any launcher to work at all. (Dayz Commander, Play withsix, Six Launcher, Breaking Point) I can launch Arma 2 and the Dayz mod without any troubles via steam, but not through anything else. It just asks for permission to launch and then nothing happens, it won't even show up in the taskmanager. None of the launchers do. When I install the beta patch, it just loads extremely quick and says "ArmA2 OA patch (version) has been applied successfully." but yet it won't show up in the directory. Put plenty of hours into searching for others with this problems to no avail. I'm really at a loss here, I can say I've tried just about everything I can to fix it. I have done a clean install of Arma 2 and CO (ran them before anything else), reinstalled Dayz, reinstalled all the launchers, ran as admin, tried compability mode, updated dotNet, cleaned Regedit and appdata, updated drivers, taken ownership of folders, and probably some more stuff which I cannot think of right this moment. I am running Windows 7 64bit. For the people who knows this stuff; I am truly at your mercy, and I really need all the help I can get. [Reason for Edit: Fixed some mistakes; added more thing I've tried.]
