Where did you research it?
There are many threads on avs and remotecentral which state that you can not get the software from URC. If you went to the URC website, you would see the following:
"Consumers and End-Users Seeking Software
Please contact your place of purchase to obtain programming support, software and manuals. If your dealer is unable to help you, you may download the appropriate programming software here.Note: that you will be required to register your serial number and place of purchase.
If you follow the link provided, the MX980 is not on the list of software which you can donwload.
I am a URC dealer, and would not have sold the remote unprogrammed, nor would I give you the software, as URC claims that:
