I must delete all my rsr files in geometries folder for running my PZ3 files.

bloody hell ! that's one serious bug - all your error messages come up in French. Seriously though Poser has no more bugs than any other program and you should just learn to get around them.

Hmm - this isn't probably a bug ... maybe you have manually (or via a programm) edited exactly these obj's - try deleting the referenced rsr - Poser corrupts them sometimes - this might help ...
