I have a MX-900 I want to replace with a newer MX-900. I have the editor software. The original MX-900 is a S/W version 1.57. The MX-900 editor is a firmware 1.57. When I connect the new MX-900 to the editor I get an unable to connect SC-1 message. The S/W version for the newer MX-900 is 2.10 (I believe - it's not in front of me at the moment).

Does the editor software firmware number need to be the same or higher value as the S/W version on the remote in order to be compatible for editing? I can edit the old remote fine and upload and download it's files to my PC I just cannot connect the newer model without the SC-1 message.

I've tried using different cables and 2 different PC's with XP and get the same behavior.

If I need new editing software, is it available?

Thanks
