I have a customer with a Marantz RC5000 that is not working properly. We programmed it a few years ago. I opened TouchScreen Setup and downloaded the CCF into the RC5000. The Home Screen came up OK, but does operate properly. No IR out or page jumps. If I touch the Home Icon, a message says "Corrupted File" and then reverts to the original version of CCF. It may possible that the CCF was built in ProntoEdit and then loaded into the RC5000. I tried downloading that way and the same symptoms occur. Did the ProntoEdit version fail because I first tried TouchScreen? Can a ProntoEdit CCF be loaded in an RC5000? One of my guys did this unit several years ago and there is no info on what or how he did it. Any help or ideas would be greatly appreciated.
