system library window in Pro render

Can any tell me how the Pro render for wf 2.0 works. When I pick system library to add a room from it it is completely empty and when I pick the + sign to add one it does nothing is this a feature that only works ARX Photolux. And even on the room editor when I open an existing room from WF Graphics Library whic have installed it makes all my walls and ceiling the color grey. Could some shed so light on this subject.


Thank you

Try changing the options pro_library_dir and pro_texture_library to point to the correct path of your graphics library.
