QTR-Quadtone RIP

I have an Epson R1800 and just installed MIS UTB (3) inks.
My OS is Windows 7 64bit. I use Photoshop 64bit with Silver Efex Pro 2 to process my prints. I have been usuing the Epson inks with satisfactory results. Since I've upgraded to the MIS inks when I print a calibration test print, I tried using both the Quad R1800 and Quad R1800-3MK printing model, the 3 black inks barely show up. I also can't get a print from already processed TIF files when I drag them into Quadtone RIP.
What to do to resolve this?
