A heads up to Win 10 users:
I updated to the 2004 build this morning, and upon completion and launch of GP, I was prompted again for my user name and license code. I was not able to successfully enter my previous code, as GP tells me I have no more activations remaning on that license code.
So it appears that GP is recognizing the new Win 10 2004 build as a different machine… at least it did for me. You might want to deactivate your GP activation prior to upgrading to the 2004 build.
To @dhj can you reset the activations for my account? I had to deactivate the license on my backup machine to get my main machine back up and running. I anticipate you’ll be getting more of these type requests.
