3.3 won't upgrade vault

Upgraded to 3.3.

Library seemed ok, but wouldn't upgrade vault. Crashed at step 4.

Based on advice here, I rebuilt the library database.

Still would not upgrade vault.

So I built a new vault. That worked, but then I added a few shots

and attempted to renew the vault and it seemed hung on 'building previews".

This was only 8 shots that I added.

I am now repairing the library again. And we will see.

Any insights would be appreciated.
