Anyone using Emulator X3 with Cantabile

I recently got a PC laptop that actually is working with my music software so I’ve been checking out Cantabile which I’ve heard about but being that I’ve been only using Mac’s I’ve never tried it out before, I also discovered that there’s an abandonware version of Emulator X3 software which is really a nice plugin. It actually does appear and work in Cantibile.Does anyone here on this forum use Emulator X3 with Cantabile? I’m having trouble authorizing it which may be a root certificate issue. I am using Windows 8.1. When I open Emulator X3 in standalone mode the registration notice appears but when I open Emulator X3 in Cantabile the registration notice does not appear. Thanks!
