Windows Live Mail stopped working about a week ago.  I need to get it working again (or at least retrieve my contact information and some old emails).  How can I do this?

Windows Live Mail was originally installed under Windows 7.  I upgraded to Windows 10 in the fall and Live Mail worked fine until last week.  MIcrosoft support said that they do not support this, but I need to get at the old information.

Original title--Windows Live Mail --
