Hi all this is my first post. I have a problem which I sure hope can be solved. I recently upgraded to Maveric OS, had problems and reloaded Mountain Lion. My problem is i reloaded Aperture 3.4.5 and I do not have access to all my referenced photos residing on my external HDD. I really hope i can get then back into Aperture there are about four years worth of photos on the external HDD.

I really look forward to your solution. Many thanks in advance!
