Opening Launchbox, I'm greeted with the attached message, which reads "Launchbox is having trouble because it seems another application is using the file". Several reboots, and verification that the Launchbox process isn't in-use, the issue persists. Clicking OK, Launchbox then loads. However, it doesn't seem to work correctly because I change the view to 3D BOXES and nothing happens (list view doesn't change). A pop-up asks me to update, I say OK, and I'm presented with the error again.
I then manually updated to 11.9 using the latest installer, but the issue persists.
