we are having a similar problem. On OS 10.3.8 with Motion 1.0.1, after we re installed the OS, motion no longer works, it worked fine for months. Now when you open it the browser pops up it gives you that prompt to ask what size template, when you pick it it crashes everytime. I have no idea why but it seems like no one else is having this problem and apple care won’t help unless you fork over 200$.
