Ok, then I don't know the answer. I've never heard the issue that people can't open the "CineEd" window (yeah, it's called "CineEd") by clicking on the task bar. What does the "Medieval2" window show anyway? Do you see the game menu or did it load directly into the battle where the camera is put below the ground? If so, can you turn the camera by pressing-and-holding the right mouse?
