Thanks for testing it Wolf. Do you use a US/English OS ?

The PP2010 OBJ file should load fine in any program. It's the PP2012 OBJ file that is the problem.

Sounds strange if you could load it into C4D if Refractive Software couldn't with their version of C4D. But maybe there are difference import settings?

I found 2 free programs that will not load the PP2012 OBJ file.

Sculptris and MeshLab.
Sculptris will crash while loading the file.
MeshLab gives this error message:  Vertex normal statement with less than 3 coords

Sounds like Meshlab also finds the problem that kawecki also pointed out in his post.
