Hi All, A little bit of an update here. I believe that I solved the problem (although I only just got Logic working without a crash). I've rebooted and reloaded Logic Pro a couple of times without incident. I tried reinstalling Logic Pro and had no luck. I decided to press on and try to think of other things that I had not thought of yet. As I was going through a bunch of the directories, I saw the Project Manager directory (silly me - I completely forgot about this). Anyway, I decided to delete the Project Manager database. I did that and now Logic Pro doesn't crash. I could have sworn that I set Logic to never check the Project Manager database but perhaps I changed the setting at one time. Anyway, I appear to be back in business. I guess the bright side is that I only lost a day :-( Thank you to everyone, especially George Leger III, for offering their help. :-) Fernstudio
