I was completely blocked out of my account making TeamViewer unavailable!
I made a change to a setting and that required logging back in.
I enter my credentials on the login screen and no email ever (couple days!) got to my address.
I did check my SPAM folder, every time!
No TeamViewer path led anywhere unless I logged in and that was NOT possible.
Even the Chat path required logging in first!
My only option was a call to the main phone number listed on the TeamViewer home page (+1 239 999 4122) and Antonio was able to get my email 'whitelisted' and thereby my ability to login restored.
Thank you Antonio!
