FAE crashes when I select the Export button.

PROBLEM/QUESTION:
FAE crashes when I press the Export button.

SOLUTION/WORK AROUND:
You may have entered non-valid option data. The problem is FAE tries to save this data between sessions and if it doesn't make sense -- oh well. FAE does only a minimal amount of error checking and you may be asking it to do something illegal. Here is the clean up process. First try the Reset Defaults button. This make get you back. If you still have problems, the best method is to reinitialize everything by deleting the FAE preferences from the Aperture plist file. To do this close Aperture and edit the file Library->Preferences->com.apple.Aperture.plist. Delete the all values that begin with the prefix "FAE_", save the file and then restart Aperture.
