When I start CCB 188.8.131.52 the message is "MMS Server is not correctly registered" . What is wrong?
I havent seen this error before, but MMS (Manufacturing Messaging System) is the core communications protocol between the controller and the OPC server, control builder, other controllers etc.
Presumably something has gone wrong registering a DLL file related to the MMS processes somewhere. Back up your projects and try repairing / re-installing control builder
