well, not sure about the 1st problem - your os/poser version/hardware/etc may help on that one. In Poser the 3d obj file needs to be in the file directory and exact name that your library item is calling. If it is a daz product than it would have the 3d obj in the proper file with its installation. If it is a zip download of a 3d item than you must do one of 2 things: unzip the geometries to the exact name of the runtimegeometriesfilefoldername*.obj OR edit the cr2 that is your library in the 2 places you find runtime:geometries:*.obj to where you have placed the 3d obj file If you dont own the 3d item and are using an add on for a specific figure than you need to go buy the original specific figure for it to work. If you own the item and the geometries folder contains the proper obj file - could be the rsr that is in that geometries folder [in which case delete it] or you may need to (if windows user) scan/defrag disk.
