I have a long-time license for X and purchased extended support just to be able to post this. The last update to X (I have it set to auto-updates) created the following message and has broken the website:
This Cornerstone license is not validated

I login to my existing account and get this page:
You are logged in as ____ . Would you like to add the purchase code — to this account?
I click yes and then get redirected to this page:
