Make sure you don't use the older receivers (non x ) with the new 12dsmx, they won't talk to them. It must be the newer style receivers (x). I doubt you did but never hurts to ask.
Kelly,
I believe the recall centered around the 5,6,7,8ch powersafe rx not the 1221. I have had no trouble running the 1221 and 9100,9000dsm2 rx with my 11x dsmx tx.
Vin...
