Hi Guys, and welcome to the forum Troy!
Gearbox was replaced by Podfarm in around 2008 I think, and if memory serves me correctly the upgrade was free.
Give it a try, you'll have to go to the software download page (https://line6.com/software/index.html) and download the Line 6 License Manager, install, run it and log in and take it from there. Your UX-1 needs to be connected and authorized.
If that doesn't work there is also a Line 6 Monkey and a Line 6 Updater that you can try.
