Crash when loading bm_c2a2

Well the game always crashes when it loads bm_c2a2.

I reinstalled the game but this doesn’t help.

SOLVED

I thought i have to ran back in the tunnels after the train crashes into a door and falls down in water.

But i was the wrong way.

So the crash only comes when you ran back in the tunnels.
