So, as the title suggests, Aperture 3 has stopped working. It no longer launches; the icon bounces for a while and then stops and says it has crashed. I have tried removing the preferences, cache, everything and it still won't launch. I've also tried ejecting my external drives which hold my libraries and still nothing. Now, what happened before it stopped working you might ask? Well, let me tell you. I had just finished importing several very high resolution film scans (~10,000x8000 at 2400 DPI) into the library and everything was going well until I double clicked one to begin editing. Aperture hung up but I figured that it was just being Aperture and being a bit slow so I waited. And waited. And waited. Finally I decided that it had frozen outright and force quit only to have it never open again. I'm out of ideas and Google search ideas on what to do, so, any thoughts?
