First of all till yesterday I had never had problems playing DayZ. I upgraded game 2 days ago and played without any troubles. Yesterday I tried to launch the game but it crashes every single time when loading bar reaches ~90%. I did remove the game. Install it once again (without any mods) and still the same problem. Game just do not start. I did verify game. I use regular launcher and tried also DZSALauncher but it always crashes at 90%. It doesn't matter if I load game or try to enter any server from launcher.
