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.

Same happening here. I've tried every posted fix. Until now the only fix that worked for me was reinstalling Aperture and updates. For me I go about two weeks until the problem recurs. Very frustrating. It happened again today. This time I tried something different. I deleted the Aperture application and dragged the Aperture application from a backup I created yesterday back into my finder applications folder. The program launched right away.


This means something is actually getting corrupted in the Aperture program file itself and not the library. Strange. While i'd prefer the program to just work correctly, my fix took about 3 seconds.
