You do not have DSON Loader properly installed. It is different from DSON Importer. It would be on your scripts menu in a line item for D3D. Again, I use a Mac and don’t know the precise Windows equivalent. You have to have the script in the script menus folder associated with the Poser program itself, which on the Mac resides in Applications, not the Shared folder where your content goes. Maybe someone who speaks Microsoft can weigh in.
