If the cr2 points to the wrong location for the obj file then you would get an error message when loading the cr2. A common cause of geometry not displaying in Poser 4 is a corrupt rsr file in the Geometries folder, close Poser then try renaming the rsr associated with the obj, Poser will build a new rsr the next time you load the cr2. Other causes might be that the object is scaled too big or small to display in the document window, or it may be loading way off in space somewhere, check the translations of the BODY and hip.
