It is best to save and backup your license email or serial number to a safe place.
If you purchased your product from the X-Plane.org store all you need to do is log in to your store account and go to the download section for that product. Your serial number is displayed there.
If you purchased your product from the Stick and Rudder Studios website or from our product listings directly on Gumroad then you would have received your key via an email. If you do need to get the email sent to you again, you can just use the contact us form to let us know you need a replacement. Please allow us a day to respond to your request.
