The website is Perim Lang Antiques, on a staging server at a new hosting provider (I can provide link privately if needed)
They had the theme installed by a previous developer who is not communicating and it had not been validated. So I bought a new version of the theme starting with the basic theme for $29 with its own purchase code, and then took advantage of an offer to upgrade to Pro which has a different purchase code.
When I enter Pro code in the validation code box it says: We’ve checked the code, but it doesn’t appear to be an Cornerstone purchase code or Themeco license. Please double check the code and try again.
I then tried entering the original code and the message says: 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 tried changing the URL from http://perimlang.com (which is hosted on the old developers server) to http://perimlang.com.user.s1220.XXX.com/ (not providing full URL to public:), but it still does not accept the Pro purchase code.
