Note: "Simple update" was turned off in the beta but will be available in the final 6.9 release. For now, in order to remotely upgrade your Hosts to the beta version use method 2 or 3 described in the section Updating Hosts in Updating Remote Utilities tutorial.
I get the same error as pictured above when I try to connect to the server using Named Pipes. If I try using TCP/IP like I did in the previous version, I get "Connection error occurred. Error Code 0." in the dialog box. Either way the server portion does not appear to be working and shows all computers as OFFLINE.
Also, the Administration and Configuration icons do not do anything at all if I click them from the start menu.
