Dear Joe,
There is an option to activate the plugin on a new domain/sub-domain/directory/sub-directory, you need to deactivate the purchase code/license from the existing domain/sub-domain/directory/sub-directory where it installed now.
Please go to the Foodbook Licensing menu on your WordPress Dashboard to deactivate the purchase code/license.
If your previous installation does not exist then provide us your purchase code to reset it to reuse.
Best Regards,
ThemeLooks Support Team
