I love this app and was very excited to begin using it. I had not trouble for the first few hours. I downloaded a few songs from the forums as a guest, then installed the editor on my Mac and created a lead sheet of one of my songs and uploaded that. Shortly afterwards the app began to crash. The first time it just hung, then repeated crashes immediately on start up. I uninstalled lost all of the songs I had loaded and created. Then reinstalled. That worked for a while. But when I re-imported my song and a few from the forum. It started crashing again. Can you help? I love the app but it's no good to me if it won't launch. Thanks.
