Just FYI, my VPN network drive is currently offline - and has been for about a week.
Knowing that, would you still need to see logs? Or would this crashing be expected behavior when a network drive is offline?
Side note- it would be super awesome if someday in a future version users could opt out of having PhotoStructure constantly scanning all of their volumes. I understand the premise, but in my case my pictures will always be on the same driveā¦ and I promise the drive letter will never change. 
Cheers,
Rodger.
