aperture 2.1.4 keep crashing

There seem to be no Aperture 2 users here right now, to be able to help you.

Have a look at the "Aperture 2: Troubleshooting Basics: http://support.apple.com/kb/HT2945"

Also try, if any of the "More like this" links to the rigth of this post have a solution to your problem.
