Problem installing cue system desk - help appreciated!

Hi all,

I have a cue system 12 channel desk and a couple of spiders and although I have set a static IP address fir the desk it cannot connect to it. It says that it recieves a reply but cannot donwload the configuration from it. Furthermore in the device discovery, the Controller IP for all the devices is wrong but I can't seem to change it...

Any help would be greatly appreciated!
