Welcome to the Magix user to user forums, so not a contact for any Magix staff and confidential data, like your version 10 serial key, should never be posted to a public forum like this one. Hence, I have edited your post to remove the second image.

To resolve this issue you need to email infoservice@magix.net, explaining ALL the details (including your order number) and ask if they will refund the $10. In my experience they are usually prepared to allow this sort of refund, or allow you to cancel the existing order (and receive a full refund) prior to placing a revised Upgrade order, especially since you have purchased the new software very recently..
