Just to elaborate on what Arthur said, in earlier versions of Lumion 2, there was a protection scheme which prevented you from loading scenes made with Lumion Free in other versions (it would crash if you tried anyway).
So you can't open a scene made in Lumion Free 2.1 Build 4 in Lumion 2.5.
However, scenes made in commercial/educational versions of Lumion 2.1 Build 4 can be loaded in later versions of Lumion.
