A problem in a registry key template

Good evening
I have trouble registering the orphan key
When registering in a new location, it shows the following message:
( Purchase code already used. Please deregister purchase code and remove theme folder on: newtownsyria.com)

Note that the attribute has been deleted from the domain mentioned and the work has been deregister


Please check documentation (online documentation will be more helpful) hope you will get help how to deregister purchase/license key from old domain. Otherwise Contact your purchased Theme Author. Contact Author and let them know. Theme Author will be happy to assist you.
