Its a set of props according to the readme file. There do not seem to be enough obj files for all the props listed, that may mean some props have embedded geometry. I dont know how Daz studio handles that.

in poser if there is a problem with the geometry file you get sometimes the bounding box thing.

first thing is to find out if its  a figure or a set of props.

I would try loading each prop individually to see which ones dont load properly. You can use geomstripper (in freestuff) to extract embedded geometries. Edit the pp2 file to point to the right obj file.
