I too was having issues, the FAQ is a joke. But what did help me was going into compatibility mode for the executable, and setting it to windows 8, and click "change high DPI settings" at the bottom. Put a check in the box for "High DPI Scaling Override" > apply >save. After launching the game, set scaling to small or it will be huge. I still have the occasional crash or corrupted save game, but this makes it a lot more playable. I was also having the mouse pointer getting jittery and hard to control after awhile, that has cleared up also.
