How do I recover POP3 emails that have disappeared from my Live Mail client??

Somehow, over the last 2 days, when I logged into my computer, my Live Mail client seemed to download all of emails from my IMAP clients again, and they came in as Unread.  At the same time, it appears that Live Mail has deleted all POP3 emails, from ALL of my personal accounts, that weren't saved on the server.  Oddly enough this also includes those saved in my Storage Folders.  In fact the entire folder structure under "Storage Folders" is gone.  Additionally there are 4 "Recovered..." folders under "Storage Folders" with some variety of today's date on them that are all empty.
