license not recognized

Hi, I am trying to install Aiomatic on my domain https://selfimprovehub.com. However I get the below error: " <div id="message" class="updated"> <p class="cr_failed_notif"> Plugin already registered on another domain, please revoke it to move the license to this new domain: http://bizhubsource.com </div> <div class="notice notice-error is-dismissible">" I no longer have access to the http://bizhubsource.com domain. I would like to  use it on my new domain https://selfimprovehub.com. How do I change this?</div>
