Two PC's, two problems, for those, who will meet them.
First one, normal PC - game restarts copmuter, when closed, no matter, how I close the game.
Reason was, belive it or not, playing in fullscreen. When I play in window and donť turn on fullscreen, there is no problem.
Second one, Notebook (I heard you call them laptop) - game can't move on after choosing dificulty, it just froze in loading. Aleready known problem here. I have easyer way to play with this problem. I made "Starters", saves created at first second in intro cinematics. You can download them for patch 444, I uploaded them. Made for each dificulty.
