My hotmail won't work. Help?

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?
