I thought I would post up my problem and what I did to fix it in case someone else runs into this same problem. Over the past couple of days, I noticed that the channel guide was only going out 1-2 hours into the future. Anything beyond that, it just said "not available" or something along those lines. When I got home today and noticed it still doing it, I checked my timers and everything is missing or gone.
I tried resetting the receiver both via the reset button and unplugging the receiver. It would never seem to try and download the channel guide.
There is also nothing in the menu for forcing a channel guide download.
So I looked online for some assistance and found a couple of ideals. The first step was to use the check switch button in the Point Dish option in Settings. This didn't do anything. I then disconnected the coax cable from the receiver and reran the check switch. Performing this, the check switch ran thru a much longer check, something like 38 things. After it completed, I told it to save these new settings and therefore deleting the old settings. This should delete all of the satellite and channel settings. I then backed out of the menu settings completely to get back to the TV screen. Once I did this, the channel guide download started and downloaded itself. After completion, since the satellite settings were missing, I had to go back and perform the check switch again. I let it run and saved the settings. It now had the all the satellite settings. I backed out to see if the signal on the TV started and it did; it also had to complete some additional channel guide downloads. It is now back to normal with the channel guide going will into the future and my timers were back as well.
