I'm confused--did you change your email address on a a different account, and would like back in on that account? If so--it's likely that Dale will be getting the notification pretty soon and allow the change (changing email accounts on your AC profile results in the system viewing you as a 'new' member, that has to be approved. If need the password emailed to you, you can request that on login--it will go to the old email account, but you should be able to pull it from there, and then login, and make the change to the email address.
