If you have a license in one website and need to use it in a different website, you should go to
Account > Deactivate License:
You can try it but if you do this repeatedly it then we are not give support for multiple website.
This is done in the website where the plugin is currently installed and you don’t need it anymore.
After you complete this the plugin will revert to the free version in that website and you can use the Pro plugin in a new website.
Alternatively, you can login to our member’s area and disassociate the license from the old domain from there.
If you need the Pro license to be active on multiple websites, we recommend you check our multi-site pricing deals
