Hi Frank. .
thanks so much for the detailed info the key to saving my aperture library was being able to copy the individual components over, adn then restoring into an aperture file, thanks for the instructions! Much Appreciated!
Aperture hasn't been able to recreate all the previews and thumbnails, as some of the original files are missing, but i'll be copying over the individual preview folder to try and save a lower resolution photos of those.
