Good news: The saves are NOT corrupted, the problem is elsewhere. If I run ToWsetup.exe and press Autodetect every time before I start ToW, it’s possible to start any game and load any saved game again. But it’s importend to do this procedure before start of the game, even if nothing is changed. The game itself says that The Screen Resolution has changed, even if it has not. My screen resolution is 1600*1080.
