Ok Ik tried some additional experiments.

I tried to load the Poser 7 scener in Carrara 5 Pro and it was asking for some obj files and the location of textures (jpg).

I also tried to  to read the Poser 7 in Poser 6 and again, missing obj files and jpg textures. So my guess at this moment is that it somehow is looking in the wrong folder. The open dialogbox show the parent folder. 

Maybe of interest this is the installed path"C:Program Filese frontierPoser 7" maybe some problem with spaces?
