Outlook Connector Problem

When I installed the latest Messenger, it gave me the option of installing
something called 'Outlook Connector', which I accepted.
I now see my msn email address listed in the folders view, but when I click
on it, I get an error saying 'The set of folders could not be opened'.
I already had MSN set up to work with outlook (can't remember how or when),
but installing connector seems to have disabled that (I can still see the
folders, but they no longer update).
So, in summary, installing connector has broken my ability to read my msn
mail.

Has anyone else experienced this and found a solution?
