Hi, I've got an install where it's got 10 EDLT's which are working and have worked for about a month however I can't edit them now. Everything else such as Saturns and dimmers/relays I can still open and edit but when I try to open the EDLT I get the message Error Displaying Unit Dialog Exception of type 'SharpCGateCommunicator.CGateUnrecoverableConnectionException' was thrown. Does anyne know what this means or how I can get round it Thanks Mike
