Live Mail 2012: Your server has unexpectedly terminated the connection. Error code: 0x800CCC0F

I am running an Acer laptop with Windows 8 and Essentials Live Mail 2012.  I periodically get this error message: Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems or a long period of inactivity.  Code is: 0x800CCC0F.    And, the error message will not go away by clicking the X on the error message window.  Need to go into Task Manager to "End Task" of Mail, and restart the program.   Any suggestions?   Mike T in VA
