CE Version limitiations?

One of my programmers is using the community edition of oFusion and can't output scenes. Attempting to do so simply closes the dialog box. Is this the intended behavior? I'd like to know the exact differences between the community and the professional versions so I can plan my license purchases.

the biggest difference for me is that the CE version does not let you export heirarchy information between meshes. So and child, parenting of meshes and scene nodes for things like vehicles and weapon mounts, or whatever is kind of tricky.

CE is good for general mostly static scenery, but not all that useful if you want to create intercative gameplay objects.
