I got 1.0.191 working with my ultra after 6 hours of frustration. The next day, I booted up, opened the software and bingo.. it is still working. I have NO IDEA what the original issue is, but I DID find that connection to ultra could be (or seem to be) inconsistent and random.1.0.191 does not work at all for the ultra. Certainly not for my setup. Fractal needs to have more support for older models. And not leave their customers to desperately search the internet for hours or days to figure out a simple problem. I wasted so much of my time trying to fix this issue. Disappointed in fractal.
