Integrate license system with FastSpring API

I need to protect my c# wpf application using a license system. I'm using FastSpring as e-commerce that allow to generate license online, so I need this feature in the dll that will be added to my app:

1. Integration of license api provided by FastSpring: subscription period / trial time / activation per version / demo activation

2. Handle the subscription period, in this way my customer at the end of that period can renew the license. If the user doesn't renew my app must be blocked for license expiration

3. Procedure automatization: there are a lot of free and open source projects on the net, but each of these doesn't automatize the task, in particular I need:

- my customer buy the license on FastSpring

- FastSpring script will add the license details in my online database (FastSpring allow to create a script in php to execute task at the end of the purchase)

- After the license generation by FastSpring script an e-mail will sent to the user

- The user go in my application, enter the license and activate the software

- The license module will check if the license exist in my database, if yes the app will activated, if no the software should't run.

More details will be provided in pm.
