If you subscribed and are billed in Kartra, Unfortunately the Kartra system 'fixes' the address a subscription product goes to.
Changing your master address will not change the shipping address. 
The only way to fix the address your subscription product is mailed to, is to cancel your subscription and resubscribe with the proper information.
We are sorry for the inconvenience.

Links to resubscribe:

If you ARE subscribed in Gumroad it's easy to change your address, but we also need to know you have done this so our shipping program doesn't fill in the wrong address.
Please EMAIL US or start a ticket to give us your new address. hello@createalong.com
