It works just fine for my alternative one. But if I try to log onto my original, it blocks it, saying 'You've tried to sign in too many times with an incorrect e-mail address or password'. It's the password I have set on it, and I always double check the e-mail address.
My alternate e-mail signs on just fine though, as does my father's.
So why isn't the first one working?
NOTE: My original e-mail ends in @hotmail, while the alternative ends in @live. Could this be a reason?
