I have changed my C: drive back to the one with Windows 7 on it, as I have had enough of Windows 10 and have decided to leave it off my large computer until forced to use it in 2020, and Dorico is asking for my activation code. I have tried the one I was originally sent and it does not work. I have attempted to write to Customer Service but am unable to log in. Can someone please point me where I can find out where to get what I need to get Dorico up and running again, please? So far my experience in trying to do this has been quite Kafkaesque!
