Appreciate your info about the box,I acquired the viewing card through the internet,a British firm who for a one off payment arranged an address for you in the UK,opened a sky account,and then sent the card out here.You them filled in a form online listing details of the reciever,which was then passed onto Sky to get the card initiated,I know,a convoluted way of doing things,but it worked,unfortunately however the website is now kaput.
I think the best thing to do,as you suggest,is contact Gary and sort it out.
