You were using a setup for you system and the new one has not yet been setup.

Such logins can have the password remembered so you need to find your password next to login with the next email login new system.

Let me state that Windows Live logins are not without a password. The PC can remember this password but Windows Live demands a password or else havoc would follow as anyone could get at your email or worse.

Normally I'd suggest you do the usual email password reset but that may be too much to ask here. Get the person who set this up to set it up again.
