I think what he is telling you is to make sure you have SR3 from Curious Labs, for Poser 5. Earlier releases were _horribly_ unstable and problematic. Your runtime. By lean he is meaning to make sure you only have the files in your runtime that your actually use (example: objects, textures...things of that nature). Most of us Poser users have _huge_ runtimes and often with tons of items we don't even use..LOL HTH -gz-
