Need to update domain name of dolphin

I have been using Dolphin with one domain name. I need to change the domain name to a different domain name. Boonex have already removed the domain name from the SmartPro license registration.

Now I need to update the license registration to point to the new domain name. I read through the FAQ page and it keeps telling me to login to the admin panel. I CANNOT login to the admin panel as the previous domain has already been moved. How can I update the SmartPro license registration WITHOUT having access to the admin panel? Is there another way to update the SmartPro license registration if I DO NOT have access to the admin panel?

Or I may need help fixing access to the admin panel.
