Live Movie Maker Won’t Load Anything, Transported .wlmp File Via Flash Drive

No matter how I load or open my movie, I always get an empty movie with the "click to add media" box. I saved multiple times prior to closing the program, and all of my work is gone for seemingly no reason. I transported the .wlmp file through a flash drive, and as soon as I plugged it in to my home computer and opened it, I could find no way to open what I actually had made. I searched all over the internet and could find no solution.
