I need to know how to restore a backup, I found one in the backups folder but how do I restore it?

Backstory: I was trying to import Shadow of the Colossus but in took 10 minutes until I tried to cancel it (so I can restart the import and maybe it'll work that time) but Launchbox froze for six minutes so then i closed out of the program then i tried to pop open the start menu on Windows but then my computer froze (I could still move my mouse which was odd) then I tried to Control Alt Delete and maybe start task manager or resart my computer but that didnt work so I forcefully shutdown my computer (mistake) but then when I started up my computer and startup up Launchbox it gave me an error. Problem: When I start Launchbox it gives me an error that says: "It appears that your Launchbox\Data\Settings.xml file is corrupt; Launchbox cannot continue. Please try restoring a backup or the file from the Backups folder inside of your Launchbox root folder. Root element is missing." What do I do, what steps do I take to restore a backup and get my Launchbox working?
