I bought an existing MX-900 from a house I that bought. I requested the programming software from URC and they send me the "MX-900 Editor."
However as I tried to download (put a new program into MX900) I get a message "MX-900 Editor us unable to download to the remote. It was previously programmed with a newer version of the software."
Also when I tried to upload (get the remote's program) I get this message that "MX-900 Editor cannot open this file. It was created with a newer version of Software. You need to use CCP (Complete Control Program)"
So can I do a factory reset of this remote and then it will allow me to program it?
A factory reset probably won't work. When the remote was programmed with Complete Control Program (CCP) it most likely got a firmware update that makes it only work with CCP. If URC sent you the MX900 editor, contact them again and explain to them that it won't work and you need CCP. Maybe they will send you a copy.
