See if they have it here:
http://diplodrivers.com/download-driver/UNIVERSAL%20REMOTE%20CONTROL/MX-880Z
they didnt seem to have the 880 but i did get my hands on the software i was looking for. i also downloaded all there software and updates so i will always have it.
Turns out we had a dealer/installer ID. they put the 880 and other Softwares into one super software called "complete control" vs. mx-880/z editor software.....
thanks for the link. im going to save it.
