Windows Live Mail Desktop Error

[Lionprowler]

My version of WLMD will not let me access my hotmail accounts.
This is the error message that appears when I try to Send/Recive:

Unable to poll for new messages on your HTTP server. There is an error synchronizing your mail account. Please verify your account has been configured correctly by first accessing your mail on the web. Server: 'http://mail.services.live.com/DeltaSync_v1.0.0/sync.aspx', Protocol: HTTPMail, Server Response: 'Client is requesting a deprecated version of the service. User should upgrade to the newest version of the client', Port: 80, Secure(SSL): No, Server Error: 4109, Error Number: 0x8DE00002

Please help if you can, thanks!
