CoD MW freezes while loading mission

Hi there. I played CoD MW yesterday and duing the last mission, where you have to blow up the factory and you fight that highly protected dude the game froze with no error message whatsoever. After that it starts, but when it starts loading the mission it freezes again. It does not crash to desktop and I don´t get an error message. It just freezes. I have to go to desktop via the windows key and then force the application to close through task manager. Has anybody experienced the same and a solution? I have already tried to repair the game and to run the game in save mode, but it didn´t work.
Thanks in adavance.
