Bluthner Sampled Piano on Receptor?

[TWB121234]

I've been checking the demos on the Bluthner sampled piano - or is it the sampled Bluthner piano? Anyway, it seems to be drawing decent reviews (Sound on Sound, Keyboard etc.). The demos sound good and it has a fairly moderate hard drive footprint of about 4 and 1/2 gigs (my 160 is filling up fast). This instrument runs in Kontakt 2 and requires the NI Service center for authorization - both of which I have on Receptor. Does anyone have experience with this VSTi on Receptor, or can anyone think of a reason that this would not work (and be able to authorize) in Kontakt 2 on Receptor? I'd like to verify that this would work on Receptor before I further consider a purchase. Thanks -
