Please send me a PM with the order number, the email address you're using now, and the new email address you want associated with it, and I can make these changes for you. Once those changes are made you should get alerts about the future episodes to your own email address.
I can send you the download link if you want to make a backup, but saving the setup file from the "preauthorized" version at that download link doesn't necessarily mean the game won't need to be activated again if you install it on a different computer. Do you know the password associated with the order? That and the order number can be used to reactivate the game.
