Aperture not opening the library
I am running Aperture 3.4.3 on a MacPro running MacOS 10.7.5 and am unable to run Aperture. When I launch Aperture it hangs with a dialog box open saying "Opening Aperture Library". When looking at the menu bar, it is showing all the correct Aperture Menu's but I can't do anything because the library won't open. I have tried repairing the premissions and repairing the library. The only thing that seems to work is trashing Aperture and re-installing which is really annoying espcially since I do not have a MacApp store version. This also seems to be happening on a weekly basis. Any other suggestions for fixes would be much appriciated.
Aperture 3, Mac OS X (10.7.5)
