I bought a 311 receiver but when I plug it in I get error 020 "The smart card currently inserted is not valid for use with this receiver". This is interesting since the 311 has a built-in card and can't possibly have the wrong card. I have contacted the seller and they are sending another receiver. They said to just keep this one - so I am trying to see if there is some way to clear the problem and salvage it. I tried a reset and next I may try leaving it plugged in to see if it takes an update. I opened it up to see if someone had put a 301 board in a 311 case but the serial number of the board matches the case so it appears to be the original board. Any other thoughts?
