With regard to your original issue, Cornerstone does not require any license validation and you only need to validate X theme. Since you're using an older version of X theme (4.1.0), our validation will not function correctly. You can check the latest version numbers from here (https://theme.co/apex/forum/t/troubleshooting-version-compatibility/195).
You can re-install your X theme or update your X theme manually (https://theme.co/apex/forum/t/setup-updating-your-themes-and-plugins/62) to resolve this issue.
Since you're using slightly older version, we always recommend to take a full site backup before updating.
