Just wanted to warn people not to do the thing I did:
In a certain stressfull moment I quicksaved while the game was still loading an area (I got a trigger happy f-9 finger). The result was that the game would not load new areas any more, or allow me to load save games, crashing to desktop every time I tried. So, I had to uninstall the whole game. Out of curiosity I tried the same quicksave move again after reinstallation and sure enough it got killed again.
So, don't do it people
