Sign in says it could not find an account with my email

This message means there is no account under the email address exactly as entered. Sign In never creates a new account, so an email address that does not match exactly gives this message instead.

1. Compare the email address against the one used when the account was first set up, and try Sign In again.
2. If no account has been set up yet, use the Create Account tab instead. If an invitation or pilot code was sent, open Have an invitation code? on that tab and enter it there.
