I can’t get my contacts and they won’t autofill?

I am using hotmail with Internet Explorer.

When I reply or try to type in a contact name on email it doesn't fill in the name or email?

My contacts list also is not available? It had been working? I have Clear my browser cache and click Always use HTTPS when I sign in to Hotmail > click Save. ll so check Enable native XMLHTTP support > OK when done.
 Try using another computer, the same problem.
