My PC has been working OK until 24 hours ago, when I found that my Inbox, Sent & Address Book were all showing as empty. I have received several messages from known contacts, to say that they have received an 'Odd' email from me, which I DID NOT send them. I have cleared the Browser Cache and run an AVG scan, but no improvement. My ISP is Earthlink.net and I am using 'Edge' as my browser.

Is there any way that I can repopulate the Inbox, Sent & Address Book, with the missing content?
