Windows Live Calendar service error “There was an error when attempting to connect to the Windows Live Calendar service.”

Original title: Windows Live Calendar service error persists

 This message appears each time I open my Windows Live mail.

"There was an error when attempting to connect to the Windows Live Calendar service. If the error persists, check to see if there's an upgrade of Windows Live Mail available or contact a service representative."

The program seems to work ok but I must remove the message each time I open the screen. I have set my computer to install any required updates. I have checked and the Windows Live updates are current.
