Hi all I have installed a c-bus system over 2 years ago and have connected to my pc using thePCU5500 a number of times. I have had problems in the past but connected by changing the virtual port a number of times. When i now open the tool kit it comes up with error 2080 eventhough i can see the pcu on my computer devices and it says it is working properly. The toolkit then closed down the project option and i cannot get to any of the projects. This never happened in the past even if i could not connect it showed all the projects on the lef and functions on top. any ideas?????
