When I signed up for Xbox Live originally I used a Yahoo account. Now I am trying to link it to my Hotmail Account. I go to My Account settings on the Xbox Dashboard, then follow the process for changes the Windows Live ID. It accepts my password for the Yahoo account.
Once I have entered the new ID and password in the next stage I get an error saying "The email address or password is not valid. Please try again later". I know that the email and password are correct as I can sign in to them both on the internet. Does anyone know how to resolve this?
