I've been playing the game for weeks consistently without any errors or crashes.
Today, suddenly, the game keeps exiting to desktop as though the game wasn't started at all.
This happens during the very first screen you get to see (with the Rat Ogre, Sister and Mercenary in the foreground lit with ominous green light).
I've verified the files (they were OK), I re-installed the game via Steam, I'm playing on a desktop computer and my GPU driver hasn't been upgraded in weeks.
What's going on? And more importantly, how can I fix this technical error?
