Original title: Windows Live Mail

I have installed windows live mail and have loaded email from 3 different email accounts. During my initial usage of this system everything was working fine. Then something happened so that I could not load anymore email message into my live email system. Every time I selected the send/receive button the mail would be permanently removed from the email servers that I had set up but would not show up on my live email system.  Where did they go? How do I fix this?
