Hey, I just looked up that H9, and it is indeed registered to your username, "rosensta2". Could you check what username H9 Control is trying to deregister the device with? If you click on the Settings button in the bottom hand corner of H9 Control and go to Eventide Account, it will show you there the username and password H9 Control is using. I would guess that it's not "rosensta2"…
I think you might have more H9s than anyone else at this point by the way. It's not uncommon for people to have a couple nowadays, and every now and then, I run across someone with three. But four H9s?!! You should send us a photo of your pedal board one of these days. Our marketing guy will lose his mind.
