mabey your model is out-of-wack.
Take out the camera control, and replace it with:
Position Camera 0,300,0
Point Camera 500,0,500
Then run it, and look at the scene (the camera should be stationary)
Then move the object around, and you should see it at some point.
When you see it, change the above code to:
Position Camera 0,300,0
Point Camera x#,y#,z#
And run it again, then the camera should point at where the object is meant to be, but if it doesnt then your model is off-centre...
I don't know how to fis that though, so you're on your own there...
Hope I Helped...
