Game loads perfectly, but when I try to turn my character there is no movement. I can rotate around the character and move foreward, backward, and side to side, but the character will NOT turn in response to mouse movement. Pressing the "R" key to change to 1st person view does nothing, there is no change in viewpoint. Because of this, I cannot activate anything, be it a door, a crate, nothing. Has anyone else run in to this, and if so, what is the solution?
Thanks.
