Activation troubles after hardware chnage

Here's what happened:

• Linked my Windows 10 Pro Licence to my Microsoft account.
• Switched out to a new motherboard, new install linked to my Microsoft account.
• Activation has failed, (Error Code: 0xC004C003) when I try to troubleshoot:
  • Press I recently changed hardware on this device
  • Select the old computer in my Microsoft account
  • Says unable to reactivate windows - try again later - and links to here:
  • https://support.microsoft.com/en-gb/help/20530/windows-10-reactivating-after-hardware-change
  • I've been through it nothing is relevant or helps
• Have been trying for 3 days now - still not activated.

Anyone got any ideas or suggestions on what I can do?

Thanks

 

Unable to activate pre-activated Windows on HDD once new hardware is installed

Greetings community. I recently changed hardware on my computer. Everything was changed accept a HDD that was installed on my previous computer where Windows 10 came pre-installed. Once new hardware was completely changed and installed, I booted up a new
computer with the message that I don't have a valid key. I went to settings to troubleshoot it, and then clicked "I changed hardware on this device recently" where I got another error, "Unable to activate Windows." I have a service key from my previous, pre-build
computer if that helps anyhow.
