Aperture error opening database for library
I was working in Aperture--deleting photos--when it crashed. My Mac Book Pro rebooted but in trying to open Aperture after it rebooted, I got this message:
"There was an error opening the database for the library “/Users/rick/Pictures/Aperture Library.aplibrary”. My only option on the pop-up was to quit.
I found a suggestion here online to find the Aperture library, hold Command-Option and double click the library which supposedly would bring up a repair menu. It didn't. I got the same message as i did on trying to open Aperure quoted above, and again the only option was to quit Now I can't even open Aperture.
Any ideas how to get my library back? Thanks.
