Just in the past two days or so, my Windows Live Mail stopped sending and receiving email.  A little popup window keeps telling me that my password is wrong.

I've tried everything I can think of to get it to working again including all the suggestions I could find on the internet.  Finally, I exported all my emails to a new folder and uninstalled the Windows Live Mail and re-installed it.  Now I'm unable to import my emails back into the program.  Plus, I'm still getting the same little screen telling me that my password is wrong even though I installed a new user name and password.  Fortunately, I can still get email on the Yahoo website, but 

I sure would like to get back to my Windows live Mail.  Any ideas would be very much appreciated.
