Save and Load from XML U3 Collections Problem

Just for fun I'd thought that I would try out THIS script on Unify. I only did it because it looked complicated and intriguing... and, even with a few modifications to save the right data, it WORKS! ...apart from one thing: Basically, it saves fine, and even saves the file correctly, but when I load the data, nothing happens. Has anyone else tried to use this script? Any solutions?
