Well, I tried the emulator on Touchscreen and it also did not work, stayed on the Home screen.

After the corrupted file message came up and reverted again, I opened ProntoEdit and tried downloading a different CCF to the RC5000. It worked OK. I then tried loading the original CCF with PE and now it works OK.

Apparently, we have an RC5000 with a PE CCF.

I am not sure how this got resolved, but the info you guys provided gave me the help I needed to try some things like the emulator to help resolve which code was used. Also, knowing that the firmware was still Marantz was reassuring as well.

Thanks a lot..........Terry S
