Aperture stuck at "Opening XXX Library" screen after updating to v3.4.5
Hi! Since I have updated my Aperture to v3.4.5, I can't open any existing libraries. It keeps stuck in the "Opening XXX Library" screen, but the application itself seems not completely hang as I can still close it.
The existing Aperture library seems problem-free as I can still open the same library in iPhoto.
I have tried to repair the library but still no use.
I have tried to start a completely new library to test the functionality of Aperture, by pressing "Option" and clicking "Aperture" icon and create a new library for testing. The same problem seems repeating, Aperture still can't even open the newly establish testing library.
Thanks for all of your time and assistance!!
Aperture 3, OS X Mountain Lion (10.8.4)
