Like others here, I started with the Marantz RC2000. Moved up to the RC3200 in 2002 and stayed in the Pronto Neo realm for 9 years.

Bought my first MX-880 from my local dealer in 2011, and he gave me a copy of CCP.. Bought a couple of MX-890s and MRF-350s from them after that. Dealer went out of business in 2014. I've been happily reprogramming my own URC remotes with no tech support for over a decade.

Now I have a bricked CCP installation and an 11-year-old installer. Found out the hard way that Backblaze doesn't back up program files by default. I'll try a fresh install of the old program on my laptop and see if a URCFrame.exe from 2010 will work, but I'm not holding my breath.

If any good Samaritan out there could supply a pre-patch URCFrame.exe, let me know.

EDIT: Got the file! Huge thanks to everyone here, for the information and the fix to get back up and running. You folks are awesome!
