QTR-Quadtone RIP

I'm having problem with curve creation on PC - the option "curve creation" is disabled. I'm running Vista 64.

I tried to uninstall-reinstall, made sure "curve creation" is checked during install, rebooted - nothing helps.

I'm trying to configure Epson 1400 with MIS eboni-6 inks. There 3 printers in QTR menu - Quad 1400, Quad1400-MIS and Quad1400-K6.
Which one I should use for printing?

Roy, I paid for QTR a few days ago. Am I supposed to get some serial # or some license?

Thanks for help,
