I also had the game crash on me on several occasions while this mission was installed. Even in the main menu, when the mission was not loaded. Maybe it's just due to 2.09 as I had to update to play this mission?
I did notice that the crashes were not nearly as frequent when I turned off the OpenAL EFX and HRTF.
Then again, I'm using an ancient PC (i5-2500, GeForce GTX 560).
