QTR-Quadtone RIP

I'm a QTR newb but a veteran of the old Piezography ICC system. I'm trying to familiarize myself with the new interface and see what's possible with color inks on an Epson 3880 before getting another dedicated piezo setup.

I'm having no luck figuring out how to soft proof anything. I see the occasional reference to profiles for the purpose of soft proofing, but don't see any packaged with QTR or anywhere else.

I've also repeatedly tried to instal the piezo k7 curves for QTR but they don't appear in the curves menu. 

Apologies if this is obvious stuff.
