how do I re key series number?
Great. So, now, we know the root of the problem. My colleague, Nick, is going to have to help you with restoring the serial number as only he can do that. I think you already sent an email to firstname.lastname@example.org about your updating problem on Friday, no? Would you mind sending another quick mail with a link to this thread, the serial number of your H9, and what kind of computer(s) you have? I think I remember you saying you have a Mac, no?
