So I opened my Spine project file today to see that all my images are missing.

I have changed nothing about the file locations. It was working earlier today, and now all of a sudden, everything is missing. I've tried typing in the path to the images in the bar at the bottom, but that doesn't seem to do anything at all. I even tried re-importing the JSON file into a new project, and that turned up all Missing images as well. Something is not right here. What can I do?
