Aperture 3.4.1 freezing after update - only on one user
Since upgrading to Aperture 3.4.1 Apeture freezes everytime I open it up. The freezing on occurs on my main user. The library works fine in other user accounts and on my other Mac. Aperture also freezes when opening any library (even a new one) on my main user account. I have tried reinstalling (including deleteing Application Support/Aperture and plist files). am downloading through the AppStore. Have also tried repairing permissions through Disk Utility and Reseting ACL's for the user.
Furthermore iPhoto freezes when launched from this user as well which leads me to believe this is a corrupt shared file between the two? any advice before I start systematically ruling out files in the library??
Thanks!
