I have received cards for my three receivers, changed cards on two of them, worked like a dream and back up in a couple of minutes. The third receiver is a 311 without card, put the new card in there and get message smart card incorrectly inserted. Called Dish and they told me to wait until I see a nag message that card is about to expire and try again. That was a couple of weeks ago and receiver has not shown message yet, tried card again and same thing smart card incorrectly inserted. Anyone else had a problem like this?
