First I lost all my contacts (2000) when an upgrade was auto installed. Now I cannot even access the Contact area from Windows Live Mail 2011 on Windows 10. Help!

I've tried everything I've read on previous posts and nothing has worked . I did the Repairing Windows Live Essentials 2011 thing, but once the repair is 100% complete, a message appears telling me that the internet connection was lost and I should Retry.  Then I went to the Options tab from the dark blue access File (top left) in Email, clicked Mail, then Connections and then Stop Signing In and Okay...nothing happened. Next I went to https://people.live.com and saw my contacts there. So I Exported them using csv., but files did not download with First and last names as I had wanted.  I don't know what to do any more.
