You can use the plugin forever. It won't stop working after the first year of membership. They have a database of Domain names and it stops working fully after you. If someone else registers a domain and you cannot make it work with Users Ultra Pro Plugin because domain is already in their license database and it won't work. I have spent about a year and the many tickets I posted were never answered. Don't buy this plugin as the support is crap after buying the enterprise edition Igot no support. User's recommendation: If you have a domain registered by someone else you could be buying a Dud.
