When playing in campaign mode, after the mission "crossing paths" when starting in the maxwell base the game freezes.

• It shows only black screen.
• The sound does work.
• Pressing ESC brings the menu, but the configuration menu doest do work.
• When saving while freezing the picture apears during the saving process but after that it returs to the previous state.

I´ve tryed to complete the previous mission but it doesnt solve anything.
