I'm not familiar with your problem, but here's a few simple things too try. I'd unplug it and plug it back in, you might even unplug it for a period of time say a half hour, and then plug it back in. You also might call your programming provider and have them do a rehit. If neither of those work, and you're sure all your settings are correct, you might try a master reset. I'd do the master reset as a last resort though, as you'll have to reprogram all the satellites which is a real PITA.
