‘Always use http’ message

Yesterday I signed into my Live.com account and it came up with a page asking if I wanted to sign in from an http website every time I signed into that account. The message explained that using an http site address would make it safer for me to access the account, so I clicked on 'Use http every time I sign in' or something along those lines. Now when I sign in I can see my usual Inbox homepage but it's formatted badly and I can't open any emails or click on any folders. Nothing works apart from Account/Options under my 'Messenger' tab and there is no option there to change my settings back to using non-http websites. What do I do?! I really need to get to my e-mails!!
