Windows 7 Live Mail

I am having the Calendar in Windows Live Mail problems. I will not let me enter any information anymore. I get all my mail but the Calendar has stopped working.  I like it because I can cut, paste, move etc. Windows sends me an error message "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". Microsoft will not help without pay so I was hoping some computer knowledge could help me.
