This update fixes some of the issues mentioned in the forums.
For those running into a crash at startup, this is 99.9% due to some hardware connected and telling the game it's a controller of sorts.
A work-around, if you can't unplug it, is:
In Steam:
1. right click on the game file and select Properties
2. at the "startup options" add: nocontroller
3. run the game.
Finally the mouse has also gotten some improvements:
It will now stick to the game window, response is slightly better and the left+right mouse buttons now also operate the menu's as you expect them to.
