Do you or your wife have another ESPN account? Sounds crazy, but it happened to me when I started doing the fantasy league and I was checking the family password spreadsheet and started entering in my wife's password instead of mine.
I'd say that's a longshot in your case, so actually I just wanted to spread the word about my misery 6 years ago and how it drove me crazy.
I got a new email: [email protected]
Send me a new invite to the league please
