Can't update my Aperture 3.0.3
I can't open my Aperture Library. I also can't up date it. I bought my Aperture as a Trial that was upgraded. I had it named Aperture 3 Trial for most of its existance but just changed it to Aperture after checking this site. I still don't get any updates available when I choose Software Update from the Apple. The Aperture is version 3.0.3 and I have just moved them to a new computer that is running Mountain Lion. When I put Aperture 3.0.3 on the new machine I could not open my Aperture library. Now I can't update the library. I don't have the original serial number for the application and can't open it. Only about 8,000photos of my kids from age 1-7 on there.... Any suggestions? Do I need to buy a new Aperture?
Aperture 3, OS X Mountain Lion (10.8.4)
