Windows Live Mail

We have a Surface Pro touch screen and had Windows Live Mail.  We were having problems sending and decided to restore back a few days to see if it might make a difference but accidently clicked on refresh and Windows Live Mail, Photo Gallery and much more just disappeared from our start page.  After talking to a computer person we were told that refresh took the tablet back to day one when we purchased it.   We were able to retrieve a couple of apps that went away and when we go into computer we can see that Windows Live Mail still exists but we cannot figure out how to get it back to use.  If we click on one of the folders or inbox a box will come us asking us to download Outlook 2013   Can anyone tell us whether or not we can get our Windows Live Mail back.  We had a large contact list and several saved e-mails in folders that we are in need of.
