Well, after many more lock-ups since the factory reset and another call to tech support, *C is replacing the receiver. The reason I was given for my needing a replacement unit is that they believe that I have an incomplete download of the CC code. I am unaware of any reasons why my receiver would not have taken the download properly, we were away from home and the receiver was powered down. I was told that the problems could not be fixed by a factory reset. The tech that I spoke to told me after reading her notice board that my receiver would be replaced because of the problems I have been experiencing. I was told of a few other persons experiencing similar problems to mine that were also receiving new receivers.
