Running Live Mail 2011, ran fine this morning.  Shut down Mail, but not PC.  This afternoon I start Mail and all previous emails in my primary account appear to be gone.  I can still see emails in my secondary account.  Further, can't see anything in the Preview Pane, nor can I open one of the emails that came in today (I get the "circling" icon )   The primary draft folder is also now empty.  I need to find a way to view the Preview Pane, open current emails and get previous emails back.  Any ideas?  Oh, Contacts are still there.

Thanks!
