HELP please.

For 2 days I haven't been able to get email via Windows Live for my MSN account.  Out of frustration I deleted the account and added it back again.  Now all my mail is GONE GONE GONE and I still can't send or receive on my account.  My Hotmail and Outlook accounts are working (at least I think - mail has been very slow today)  My Kindle and smart phone are working too.  What is going on here and how can I get this back on line?
