ok, so I have followed all of the steps in order to be able to play Day Z, my problem is that whenever I try to Launch Arma 2: Combined Operations, a black comman type window pops up for like half a second and then disappears, and Combined Operations never runs. I am able to run Arma 2 and AO but whenever I try to run Combined Ops the above happens. I have uninstalled and re-downloaded numerous times, and I originally purchased the Combined Operations package through Steam, any ideas? and if possible simplify the instructions on what I need to do down, as I am not a wizard with a computer. Thanks for any help!
