Windows 10: Windows reactivation after hardware change - error 0x803FABB8

I've replaced my old motherboard + processor today and since then windows 10 is demanding an activation code. I had already activated windows before on this computer and it tries to activate it with the information it already has but then it fails with the error 0x803FABB8. It says that I should try again later or buy a copy in the store. It's been about 6 hours since I first booted my pc into windows with the new hardware. The help pages about reactivation problems couldn't help my case. Any ideas about what I can do now?

windows 10 reactivation after hardware change

I just changed motherboards, and When I follow the the steps listed in the "reactivate windows 10 after hardware change" support page, it gives me the message "unable to activate windows" message after I sign in and identify my device,
with no error code, just a subheader that says "can't activate windows 10 on this device, try again later."

Windows 10 won't reactivate after a hardware change

I changed a lot of the hardware on my device recently, however I followed the steps on the Microsoft support page to get my computer ready for the hardware change so that I could reactivate Windows 10 after I changed the hardware. However, now it won't reactivate,
and has the error code 0xC004F025, and when I try to troubleshoot it says "We can't reactivate Windows on this device. Try again later."

My Windows 10 was a free upgrade from Windows 7.
