OK, so I now deduce that you are trying to import a scene for which you did not create a Poser companion file. I recommend you install D3D DSON Loader (http://d3d.sesseler.de/index.php?software=poserpython&product=dson_loader), which will let you manually import your duf file from DS. There is no need to copy any of your data or textures to the Poser runtime. It will use the information in your DS data and runtime.
