X license is active, but Cornerstone is not validated. Cannot validate Cornerstone

[gcsgroupus]

I just bought a new license for X. I activated it using the license code. Version: 10.1.10

Now I have a message saying: This Cornerstone license is ​ not validated ​. [Fix]

I click on Fix, enter my license code, and get this message:
This looks like a brand new purchase code that hasn’t been added to a Themeco account yet. Login to your existing account or register a new one to continue.

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:
https://theme.co/undefined

Hello @gcsgroupus,

Thanks for writing in! You cannot use the X theme license code to validate the Cornerstone plugin. Normally, when the X theme is validated, the Cornerstone plugin will NOT ask you to validate it. If it does, it could be that you renamed the x folder or that you have uploaded the incorrect zip file.

To better assist you with your issue, please provide us with your WP access so that we can check what is causing the issue. By the way, are you validating the site assigned to the license code as shown in the screenshot in the secure note below?

Best Regards.
