3d preview not working! anyone else?

hi all!
I bought yesterday the 3d preview cup but for some reason is not working!
I have put the folder here

and i can see the dropdown with the 3d preview selection 


For some reason that i dont know, i cant see the preview no where!
I setted just on one product to show the preview outside the lightbox (to check quickly if something happens) with no success

and i tryed to mannually put the shortcode [fpd_3d_preview] but is not recognized as a shortcodes and its shown as a basic text!


any suggestions?
Thank you
