Hey there, Just wanting to see if anyone has had similar issues with opening the GUI for edlt. We installed the system and programmed around 9 months ago. The system has 82 units on it and draws a current of 1750 ma there abouts and has a supply of 1950ma. Have programmed a dimmer unit with a power supply to be 001 and enabled two clocks and 1 burden. All the units have sufficient voltage the lowest being 24.7 and the highest 29.8v this is across the network. The toolkit scans network fine and has done all the way until now. Only the edlts do not scan and imeadiatly a prompt note comes up saying fatal error. There are a few other texts in the msg which I can describe if needed. And also it’s a forced cancellation of trying to bring up the GUI for the edlt. All other units open up fine! I have reinstalled a lower version of toolkit 1.14.4 to match the firmware of the edlt to which it made not a difference. I’m not a computer buff by all means but could it be possible that my laptop has something to do with it. Lastly the system works fine other then the issue with the edlt when I want to make changes to then Cheers
