I'm using 3.043.066. The pc isn't connected to the internet but I will have a go at updating .net and see if it helps. At least now I can change stuff in the plugin and save it now so it wont stop the machine from working I hope.
I have emailed cslab tech help with the photos so I will update this thread with that info when they reply.
I now need to sort out a tool height setter and get it functioning.
