Linking the DAZStudio library to the Poser Library, the same way you would link any runtime folder to your most current Poser version.  That relationship has always been a two-way street.  Sometimes, DS geometry would be loaded into its runtime folder with the possibility of Poser missing it if the libraries aren't linked.  Essentially, accessing reference material.  I don't know if this is the case with your problem but I haven't had any major problems with importing figures from DS because the libraries are comingled.
