I am desperately hoping someone can help me…I have an iMac (only a year and a half old) and the drive pretty much just died on me (spent 5 hours at Apple store Tuesday and countless hours on Apple support) Anyway, I bought a MacBook Pro to have something else while we try to figure out a way to access my iMac drive (I didn'thave EVERYTHING backed up (Grrr…I know) Anyway, fortunately I have most of my Aperture libraries on external drives but now I have run into another problem. I downloaded the trial version of Aperture (wile I figure out how to get the code for the previous copy I bought) and I tried to open my libraries. The problem I ran into is that I believe some of my libraries were created with Aperture 3.0 (not this current 3.1.3 which is on my iMac.) In any case, when I finally was able to open a couple of libraries, I can see all my projects and albums and I can see the squares where my images should be - but I can't actually see the image! I see the file names, the ratings, the color code but no actual image! Can anyone help me ???
