This past Friday, for one night only, I was getting a 359 Error Message everytime I selected an HD channel with a warning that my Smart Card would expire on April 9. The message instructed me to call Cusomter Service if you haven't received a new Smart Card. I called and CS said they would send me a new DVR/Receiver as that would be easier than having me replace the cards as I have a 622 and a 222. I went for CS's recommendation, but now have second thoughts. Won't I lose all of my 622 Timers and recorded programming when I replace the 622? Can someone tell me why I even need to replace my Smart Card and secondly why did the warning go away, I haven't yet taken any action.
