Your EZGenerator license comes with a 1-year update subscription.
You have full access to all templates and program updates during 1 year.
After the period of free updates, if you want to get further updates you should subscribe for a new 1-year update subscription
It is NOT REQUIRED to get 1-year update subscription, you can use EZGenerator without subscription if you don't need updates.
You can pay for subscription later when you need updates again (which will give you rights for updates for next 1 year).
When your update subscription gets expired, this doesn't mean EZGenerator is expired or unusable, you can keep using software and already downloaded templates.
