We changed our website name from isynergo.com to isyrgo.com because there is a domain name similar to isynergo.com. Now we try to activate the License Key to our new domain name and the message say “License Key is Used”. Please help how to activate the plugin.
As I see you have used your license key for two sites – isynergo.com and syneraid.org
But you can use it only for one site. I removed the license key for the both sites. Now you need to activate pro version one more time on your new domain. It should work correct after this. Please use the license only on the one site, which you need.
