I have an invalid G-Mail e-mail address in my profile which I cannot correct because every time I try to change a setting it requires me to validate my account and tell me it sent an e-mail to the INVALID e-Mail address to fix/validate. Not only can I not access this invalid e-mail account, nobody can because it does not exist. I am in a catch 22 and can not use my Dropbox. Please advise as I cannot even use Chat which requires a validation that is sent to the invalid and nonexistent e-mail account!!!
