I am working up in Montana and I have one of my home receivers with me and all has been good, however, I pay for Center Ice but the channels are telling me to order them and giving me error code 721. The question is if I call them and have them resend signals will it work to the receiver I have with me evn though I am across the country with it or do I have to tell them I have it in Montana? Is that something that is permissable with them? Thanks, any info would be appreciated.
