Cumulative Update 8 broke Exchange 2013

While installing Cumulative Update 8 on our exchange 2013 server it failed with the following error during the second to last step (client access role: client access front end).  Any advice on what may be causing this and how to fix? 

Error:
The following error was generated when "$error.Clear();
          $fe = get-ActiveSyncVirtualDirectory -server $RoleFqdnOrName -DomainController $RoleDomainController -ErrorAction SilentlyContinue;

          if ($fe -eq $null)
          {

          }
          else
