Xtreme vs Xtreme Pro 3D?

I have been using Xtreme Trial version to create websites and I am ready to purchase. I downloaded Xtreme Pro trial and loaded one of my files. It would not display a 3D extrusion. The Xara website shows a comparison that both products support 3D. Does Xtreme Pro handle it differently? Or is it an issue with the trial version? I want to buy the Pro version if it is compatible with the work I have already done.

Thanks,

Philip

As far as I am aware, there is no difference with extrudes created with XX4 and XXPro4. Anything created with XXP4 is compatible with the Pro version.

Could you attached the XX4 created .xar please?
