I have Windows Live Mail 2011.  Yesterday, it suddenly stopped working.  It was as if it wasn't configured for my computer.  I couldn't see any of my emails, etc.  I was able to get the situation fixed, or so I thought.  But when I tried to send an email, I got an error message.  I reentered the settings for my email server (earthlink) and now, nothing works!  The program doesn't open or anything.  The only thing that happens is the small box that appears when email is downloading or sending appears, but nothing happens.  How do I get this thing working again?
