Game Freezes in Monastery

[preserver]

After i got Kruger in my team, he reveal several places in the map including the monastery, where i'm supposed to kill all the monks. After i kill the last monk, the game screen blanks and goes into what appears to be a cutscene (i'm guessing from the arrow-cursor turn into the camera-cursor), and it just freezes until i shut it down from the task manager. This happens everytime.
What is happening here? Can somebody help me?

By the way, in the message.log file i got this:
