Thank you John and Russ!

I finally managed to get the Control:PC up and running. The only problem I now have is that I am unable to get music out of the ID41 or USB. I will double check tomorrow as most likely I have done something wrong in setting up the 818. I have included in the config file that there is a Sooloos system and it points to ID41 (designated to AUX/SLS).

Thanks again for all the help.
