Hi, I am having difficulty lanching and playing vanilla DayZ (using steam). I have installed DayZ commander and it tells me all the game installations are up to date. I join a vanilla DayZ server from the list, one which has a white font colour, not grey, and DayZ launches. During ARMA's tickbox launch window, one box is ticked then the game returns the error: "!!! MISSING STRING !!!" I close this and the launch continues. Still on one tickbox and the game returns: "Application load error 5:0000065434" It returns this twice. I close these and the launch continues. 8 tickboxes in, and the game returns: "Failed to load file: E:\Program Files (x86)\Steam\steamapps\Steam Library\steamapps\common\Arma 2 Operation Arrowhead\baf\addons\air_d_baf.pbo - decryption of headers failed." (Please don't judge on the insanely long steam path :/ ) Finally, DayZ starts in windowed mode despite the fact I have it set to fullscreen and I am immediately kicked from the server, last time I managed to catch something about versions in the chat in the split second before I was kicked. Verifying integrity of ARMA II, Operation Arrrowhead and DayZ doesn't solve any of these problems. Version #s (according to DayZ Commander): ARMA: 125548 DayZ: 1.8.3
