All of a sudden I cant click on a new email without getting error messages including the one in the message header. Also when I first start windows live it takes a long time to start and tells me its accessing windows live back-up.

I am unable to find a solution for this as I have uninstalled and reinstalled 3 times now as well as tried repairing it and still im getting error messages on every new email I click on as well as being unable to send emails.
