We had four email addresses linked with Hotmail, now I can’t access three of them, and when I try to sign in it keeps automatically taking me to the main address!

We have a "formal" family email address we use for business or job applications etc, and three email addresses we use for facebook and games. Since the "upgrade" we can only access the main one, and every time we try to log in we automatically get directed to that one, so can't even sign in on one of the others. Permissions seems to think we want to link with other people. We don't, we just want our four email addresses available on the same page! How do we get this back?
