Are you saying that you have your "Libraries" and "Geometries" folders in a folder named "renderosity" and not in a folder named "Runtime"? The Poser.exe and Poser.rsr files can be in any directory BUT... the remaining files and folders for Poser must be in a directory UNDER that one and must be named "Runtime". Poser's file structure is very picky and most of it cannot be moved or renamed.
