I have just bought Dishonored yesterday and it worked fine, but now sometimes when I open a door that goes to a different area a box pops up and says Dishonored has stopped working. The game then closes and when I start it up again it erases my last autosave. There is no place where it has happened every time but frequently it is when I've been detected and running from guards.
The text of the error message says:
Dishonored stopped working
