The site works only with ArchiCAD 16. This is because it is tightly integrated with the program and only ArchiCAD 16 code has this functionality programmed into it.
You can drop individual objects to ArchiCAD with the appropriate button on the page of the given individual object.
Or you can download full libraries but you will able to use those only in ArchiCAD 16.

I'm using Archicad 16 now and still can't download any object. I suppose it's the button with an arrow, I click it but nothing. I'm using archicad in spanish by the way, don't know if that has something to do with it. I see the 3d object, settings and all in the website but I just can't download it.
EDIT: Nevermind, just figured out the download thing.
