Turn off Windows Firewall and then reinstall CCP
Yep, good idea, didn't help. Michael at URC told me to do that. I suffered through the last necessary items of the MX-980 and managed to forget my USB to RS232 adaptor to update the 850s, so I don't know if they would have had problems, too.
One thing nobody has touched on is whether there might be some problem with the file that was in the remote when I got there. (I once had a Marantz RC5200 file that kept resetting itself to factory programming and nobody was ever able to figure that one out. It could be the remote or something squirrely in the file.)
