Images not selected in SyncToy preview

[Guest]

I got back after a six week trip and ran my SyncToy action to Contribute
photos from my laptop to my NAS; I left it running overnight and in the
morning I saw it reported 641 files not copied. through the usual Tired User
Error I closed the window rather than looking at the error log. Now when I do
preview on that action all the files are marked as new - but none of them are
selected. I don't want to click 641 checkboxes! What can i do? Can I see the
error log still? I have restarted SyncToy since the error but no change...

I found the right-click Select All (is it just me or is that an obscure way
to do it? I'd have liked a master check box at the top of the list). But I'd
still like to know why the files got stuck as not selected. Any ideas?

Also - how about an Export partnership option for when I get a new PC?
