My younger sibling set up their Nintendo Network with an email address that is no longer active, and we can't reactivate it to get the passcode to link his #DS system to the Nintendo Network and he needs one to play his games/update his system/shop on the store. Is there anyway that we can change what email address that is linked to the Nintendo Network, or some way to restart the process so that we can make it so that he can hook up to it?
Thank you
