Remove the card from the 4100 this will bring up the System Info Screen. Here you will see what the Remote address is, I am guessing it is NOT the same as the Remote.
Replace Card, this will cause the receiver to re-boot and re-download the guide etc.
This may just restore the programming if it has not been out of the datastream too long but anyway, now go ahead and change the Remote address as you did before.
If programming does not come back, log in to Bells' web site and find your way to Synchronize programming. If all else fails, you will have to cal Bell.
