The purchase code already has been registered. Could you deregister purchase code on the another domain and try again.

Basically when you changed your site url or domain name such as to or http to https you will get this message.  So now you need to create a ticket for it we will reset it for you.

If you wish to switch your domian or install the theme in another domain you need to deregister the purchase code from your existing domain first via Theme Options > License > Deregister.

If you deleted the site without deregister then please create a ticket for support we will check our account and deregister it for you.
