Hello, I got this game last night, and watched all the tuitorials on how to play. I went to sleep shortly after that. Now im trying to play, and when I go to rotate the camera, nothing happens. The tutorial said hold the middle mouse button, the only button in the middle for me is the mouse wheel(Which can be clicked, but it didn't work when i tried it).

Is there some way to alter the controlls so that I can get this to work?
Edit, mis-spelled camera.... twice...
