Crashing + can't fly a plane *pc*

[Futurezx]

When i am in a plane and press W it's only moving the wings from the plane.. it isn't moving or anything + when i press the Space bar inside a plane my pc crashes, any solutions?

So the airplane doesn't even move when you press "LEFT SHIFT" and keep it pressed? Because "W" is for your steering, once you are up in the air...
