I have an @msn.com email account.  Recently, I used hotmail to view email as I was in Europe.  I've been back several days and no problem until yesterday.  Suddenly, my MSN mailbox is empty but the Hotmail inbox has the email.  I do NOT ususally use Hotmail and don't want to.  How do I get my mail back into my MSN mailbox.  (My "folders" and contents are all on MSN.)  Help!
