Cant open windows live Hotmail from Visa and One Care

I have been trying to open my 2 Windows Live Hotmail accounts from Vista
Home Premium running MS One Care. I just cannot open the hotmail accounts.
They appear on the Live mail screen with logins but when I try to login it
keeps trying to open several times [guessing 12 or more] and lines up tabs
on the browser but in the end I get an error message that either the site
may have a problem or I might not be a member. I can go directly to my XP
sp2 computer and login.

I have tried right clicking on the login name to open in a new tab but that
still does not let me login. It is so repeatable it has to be a known
issue.I am suspicious it is a One Care problem. I hope someone has a
solution.
