Thank you both so much for your replies! I found the original "_TBSW164 Demo (Country, Nashville TeenBeat with Piano).SGU" on a backup drive and I copied over the bad one that I created. Now when I select "Load demo song(s) for the current style" it doesn't load anything. I can load the SGU file manually but the "Load demo song..." doesn't work for that song only. I've tried other nearby styles and they all work but that style refuses to load any demo song at all. It just keeps whatever song is currently loaded. No error message. Is there a database somewhere that is missing the data for a field? How does BIAB determine which song to load when you click on "Load demo song..." ?
