Unfortunately I have a similar problem. I tried to update my Universal Control (after the software prompted me to upgrade), and I already had Studio One open. So, the Universal Control couldn't finish the update, I had to abort, and then I could not get it to work until I uninstalled and then reinstalled the UC software. Now all of my mix presets are gone. Such a waste of time. I'd love to know if there is a way to avoid this situation in the future.
