Methods and systems for securely distributing software in a subscription-based environment are provided. A Game Security Facility (“GSF”) associated with a game server manages secure communications with game clients. A subscriber is registered in a manner that includes a unique identifier of the machine upon which the subscription data will reside. Encryption keys are generated for the registered subscriber and encrypted subscription data is exchanged, thus preventing unauthorized copying to another machine or unauthorized use by a third party. The subscriber is re-registered, and new encryption keys are generated. Access is enabled to the previously exchanged encrypted subscription data without causing the previously exchanged data to be re-downloaded.
