Hello @BillProtzmann ,
I completely understand the importance of changing a subscribers email address, and apologize our site was giving you trouble. Are you able to provide some additional information, such as the status of this contact? If a contact is 'Confirmed' (They went through the Awaiting Confirmation process and explicitly confirmed to be part of your list), then that email address is unable to be edited due to legal reasons. However, you should be able to edit the email address otherwise if that's not the case.
Was the screen grayed out when you attempted, or did it throw some sort of error?
