lost Windows Live Contact list

Windows 10 installed itself on both my computers (without my knowingly okaying it...).  Everything seems okay... except that my email contacts are lost/not found!  I am NOT using the Windows 10 email and 'people' stuff.  I AM using the Windows Live Mail that I have been using since forever (at least 2000?). I actually found the 'contacts.edb' file that was explained in another post, but I cannot find how to get the WLM to use it again.  Importing only asks about an online source, not my own computer.  I hope someone here can help, and fast!  We have probably 500 contacts in there, and most are business for my hubby!  Thanks!   --Laura Meyer
