Cannot access my Aperture library
Please help - I cannot access my photos any more. I have >400Gb in my library and all attempts to access it have failed. If I click on Aperture it says I do not have the right file permissions to access. I have read and write: I unlock it in Finder but there is nothing I can do. I looked in Disk Utility and tried First Aid, but the Repair Disk says it is ok. I have held down Option and Cmd and double clicked on Aperture, and have attempted to repair the permissions - it gets half way through a check then says "Could not enforce consitency of files". The other options to repair do not work as it says I have the wrong permissions!!
My only idea now is to put my old discs for Aperture in and apply updates, as the library won't be readable on old versions. Any ideas welcome ...... please?
Thanks, James
