put the .obj files that don't work in the same folder as the ones that do work, all of vicky's clothing .objs are in the same folder. second thing to try is to delete all the .rsr files for these .objs (the ones in the geometries sections not the ones in the libraries section) sometimes the .obj's partner .rsr get corrupted, don't worry poser will rebuild these files when you use the item, but it will slow down for a second or two when this happens.
