And I quote,

"The MX-980 is programmed via a windows PC equipped with a USB port (progamming cable included), using our proprietary software, MX-980 Editor. You could download this software from our website: www.universalremote.com"

PAGE 4, from the Operating Your System With the MX-980 pamphlet that comes WITH the remote.

Not that I'm a lawyer or anything, but if the documentation from URC says I can have the software, and I bought the remote because URC said I can have the software, and URC doesn't make good on their own promise/pledge/offer, sounds like a lawsuit to me.
