If X-Plane does not find valid DRM files at launch, it should give you the option to enter your product key to unlock the simulator. When you start the sim, the very first screen should be a box to "Unlock X-Plane."  Pick the button on the right (Unlock full version) to enter your product key and unlock the sim. If you are not able to authorize, make sure you have a valid internet connection.
