Hi Everyone I have a 2012 MacBook Pro with the latest update of Aperture 3. Last night I decided to backup my Aperture manually... by dragging my ApertureLibrary.aplibrary (231 GB) to my external hard drive. It finished transferring and now when I try to open Aperture, it tells me: Only problem is I didn't use, nor have I ever used, Time Machine to back it up. I tried repairing permissions, repairing database, and rebuilding database. I've shut down the computer, turned it back on, etc. Nothing works. I feel kinda safe that my photos aren't gone cuz the file is still 231 GB, but I can't open Aperture now!! Please help!! Thanks in advance!
