I have an Echostar DSB-890 2ci receiver. I bought a Dragon cam (latest T-Rex model) and a Dynamite programmer and a F84A Dragon Loader card. I tried programming the card with various Predator files and it said it did it OK each time, but when I put the cam into my receiver and display the CI menu, my receiver says "not present" for each CAM slot. At the moment I'm thinking I might have a duff receiver or a duff cam or maybe just a duff understanding of how this all works (this is my first cam purchase). Any ideas? Thanks in anticipation.
