Hi Marlene,
Thank you for contacting us and I'm sorry about the issue you are experience. I don't understand your request here. It does not appear that you purchased a license directly from our website. Because of that, there's no way we can provide you any kind of receipt. Please use the app store that you used to purchase a license with in order to view your purchase history and any receipt you need.
