Has that NX-RM820 editor software worked for anyone that has the latest MX-850 remote from URC?

I just got that editor and compared it with my MX-850 editor. It's even older than my editor software. And of course, it doesn't work with this new MX-850 remote I just got. Works fine with the older MX-850 I bought in 2007. But as you all already know, URC changed not just the MX-850 hardware, but the serial protocol it used to talk to the editor software. That's why the new MX-850s can't talk to the old editor software.

And I can't seem to find the new updated editor anywhere and I an *NOT* going to shell out $99/pop every time I need to make a change.

I'm at a loss here. I'm willing to shell out some cash to buy the editor software, or does anyone know of any good alternatives to URC remotes?

Thanks,
