In order to use an extension you will need to create an Application Key and pass this key into the
Extension.init( APP_KEY ) call of the extension. This should only be called once.
Application keys are linked to an Application ID and can only be used in the application that has an identical ID. If you add a new extension you must recreate the application key for that application.
The application keys are a form of anti-piracy that we introduced several years ago and are currently phasing out.
The extensions do not contact our servers to verify application keys.
The keys will never expire and we cannot cancel them (nor do we want to).
Your application keys will never stop working once created.
To clarify, the yearly subscription cost is for access to updates and support
and is in no way tied to your usage of the extensions.
We want you to be able to use the extensions forever.
