Black Plague - Research Facility crash

[tacc]

Everytime I try to enter the Research Facility (in the Building after you were outside for a bit, Door requires a Key Card) the game crashes.
I use the Card, click on the door, loading screen appears, crash.

Tried to reset all the settings, load an older savegame, verified all files and tried 2 patches which aren't supposed to be installed on the Steam version.

Had the same problem with Overture at the Last Chapter (http://frictionalgames.com/forum/showthr...p?tid=3317). But a Patch doesn't help this time.
