I've tried. I get the above message when I put it either into place or just on my desktop. It's like it's fighting me, not wanting me to get all my stuff back.
First off, am I even doing it right?!? Going back in Time Machine to March 7th or so, navigating to the iPhoto Library file (14.7GB), selecting it, clicking "Restore" and then...???
That's when it all falls apart. I would've thought it would bring it up to
today's Finder window/Photos directory, maybe prompt me to restart iPhoto, rebuild/restore everything as it was, I'm happy again, etc.
