Papervision 3D Cube Tutorial Problem

Hi guys,
I’m playing around with papervision and i’ve followed this tutorial:
http://www.gotoandlearn.com/play?id=40

I wrote the code as the tutorial but i have some errors…
Here the code: http://pastebin.com/KeRaHBxY
And the errors are:

1046: Type was not found or was not a compile-time constant: Plane.
1137: Incorrect number of arguments.  Expected no more than 0.
1120: Access of undefined property bam.
1120: Access of undefined property bam.
1180: Call to a possibly undefined method Plane.
1120: Access of undefined property bam.
1061: Call to a possibly undefined method renderCamera through a reference with static type org.papervision3d.scenes:Scene3D.

I’ve flash cs4 and i’ve downloaded papervision 2. I followed the tutorial but i have this errors…why?
