Hey @cute, I'd be more than happy to help look into this with you.
Have you made sure that you're entering the updated email address?
Do you have any notifications in your inbox of the "new" email, like a Dropbox verification email?
Let me know what comes up and I'll make sure to get back to you as soon as possible. Thanks!
