I have ran DayZ before and used to play alot. When I attempt to return to play more I seem to notice problems which stop me playing the game. The problem When I click DayZ commander, I get the User control screen comes up (would you like the following program to make changes to your computer) there is a yes and no button. I click yes. the loading circle is there for a split second and then nothing. I will not load up. I have tried many things, from reinstalling DayZ commander, to reinstalling the whole of Arma 2, OA, DayZ mod and the commander, I have ran as administator, disables and enables visual effects mode and tried running and not running in compatability mode. I have tried another launcer (PlayWithSIx) which I downloaded and encountered the same problem. There must be something stopping me opening these programs and I have no idea what. Any help will be appreciated,
