I just loaded the Phoenix Simulator for Horizon Models and can't get it to work. It won't recognize my DX5e. It does know when the cable to the DX5e is connected but doesn't see the transmitter. I downloaded the latest update with no luck. So far a big waste of money. I run Realflight 4.5 without any problems. I have a newer computer with a Quad Pentium and 4 GB of memory.
