Windows 10: Windows 10 can't be reactivated after a hardware change

So I swapped out my motherboard, CPU and memory yesterday for some high end stuff and now I can't reactivate windows. The trouble shooting windows just keeps telling me that it can't reactivate windows right now. I also tried re-using my serial key but then it says it can't activate because it's already in use.
I'd rather not buy a new windows 10 key.

Who do I have to bother to re-activate my windows?

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.
