Windows 10: Reactivation of Win 10 Pro (purchased in Jan 2019 and Office 365 because of motherboard...

Hi, I bought Win 10 Pro in January 2019 and renewed my subscription for Office 365. I had to change my motherboard yesterday and now cannot re-activate either Windows nor 365. I have done the troubleshooting steps repeatedly and it seems like I am caught in a 'do-loop'.

Office 2019

Only supported on Win10. Sorry, 8.1 users, only 4 years old, gotta go.

Microsoft Office 2019 will only work on Windows 10

Spoiler Office 2019
Last year at Ignite, we announced Office 2019 – the next perpetual version of Office that includes apps (including Word, Excel, PowerPoint, and Outlook, and Skype for Business) and servers (including Exchange, SharePoint, and Skype for Business). Today we’re pleased to share the following updates:

• Office 2019 will ship in H2 of 2018. Previews of the new apps and servers will start shipping in the second quarter of 2018.
• Office 2019 apps will be supported on:
  • Any supported Windows 10 SAC release
  • Windows 10 Enterprise LTSC 2018
  • The next LTSC release of Windows Server
• The Office 2019 client apps will be released with Click-to-Run installation technology only. We will not provide MSI as a deployment methodology for Office 2019 clients. We will continue to provide MSI for Office Server products.

 

Office 365 to Office 2019

If I change from the subscription Office 365 to outright purchase of Office 2019, will I lose my documents?

 

Microsoft Office 2019 Will Run on Windows 10, and Only Windows 10

My understanding from reading else where that MS plan to stop supporting Office 2019 the same day they stop supporting Office 2016. I wonder if that a sign that Office 2019 will be the final one time pay version and after that office 365 will be the only option.
