Well, no. There is a folder called Masters but nothing in it. No Recovered either.
I have Time Machine back up. The Aperture Library from there looks like it still has all files, so I have copied it onto my hard drive now. I'm just about to go into Preferences and change the Library Location to this library. It now tells me:
"The selected library is from an older version of Aperture and requires a relaunch to switch.
Choose “Relaunch” to relaunch Aperture with the new library."
Shall I do it - will it help? Or is there another way to do it?
Should I rebuild this copied back up first?
If I press ALT+CMD and double click on the copied back up library while Aperture is open, it asked me:
"Do you want to import the library “Aperture Library BU”?" Would that be a better way?
You seem to know what you are talking about, so I'd love your advise before messing things up further.
