No Shaw Service in USA

We left Canada today and only drove into Montana. We have a travell'er Winegard system. It found the satellite immediately but NO picture. I used my US CELL phone and called the 800 number with no problem and asked for a "Refresh" by using the number keys. That part worked fine but still NO picture. I went into the options menu and I could see that the "TRIP COUNT" was working. I needed a major "DOWNLOAD" which I did myself and about 3/4 of an hour later I had a TV picture. I would highly recommend that before leaving Canada you set up or use your receiver for at least 24 hours so that it will do and have all the latest downloads in the receiver before you leave just in case you have a problem so you can talk to a tech while still in Canada. If you know how to do system downloads then fine but it may still be a good insurance just in case. Keep in mind this would only apply to users that do not use there receivers in their house while in Canada. My receiver had NOT been turned on for about 2 months.
