Windows 8 Backup Problem

OK after applying the recommended hot fix I have same problem but it has worsened   

Backup will still not run.  Never goes beyond 0% now.   In the dashboard I NOW cannot even go into the backup configuration for the client to limit the scope.  The error is:  An unknown error prevented the server from performing the task.  Make sure all services on the server are running, then try again.  

Client event log says Backup did not complete because a problem interrupted a connection to the server.

Backup Job 0 did not succeed - connection lost  System string

Can you advise next steps forward to troubleshoot this?
