Update your .NET Passport profile. Go to www.passport.com Click on the heading called Member Services Under the 'I want to change something' header, click on: 'Edit my .NET Passport profile' When the .NET passport sign-in screen appears, sign in using your email address and the corresponding password. Edit any and all info. Re-do the whole thing, even if it is correct. Do not leave any fields blank. When done, press the Update button. Might take a few hours for the update to take effect.
