I have a strange issue as well in trying to register my H 90… After accurately entering the serial number I receive a message that the serial number is invalid. So I cannot register it, and I cannot download Control. I tried numerous times with the same result each time, I even tried omitting the hyphen and using lowercase rather than uppercase… Please advise.
