Live email

I have been using live email for years and about an hour ago, after i ended a first time Citrix webinar, my live email wont work..it keeps sayingI am offline, but the icon shows I am logged into my Microsoft account but whenI hit send receive, it keeps telling me that I am offline and do i want to go online...when I click the go online button, it doesnt work, the sending for new messages box says connection was interrupted
