Database schema update failure

This morning I upgraded Image to 5.x-1.1, and run update.php with no problems.
I then upgraded Acidfree to latest 5.x-1.x-dev, and run update.php with no problems.
Following editing of an album image the system warned me about the db schema needing an update
Running the update I got the errors listed below (Drupal database update)
Checking the log I see the errors listed below (Recent log entries)
Maybe unrelated, Earlier on I had noticed the logs complaining about missing item: art/play_big.gif
I have a backup from last night but I am not familiar with db administration:
which table(s) should I restore? Should I "downgrade" acidfree too?
Any suggestion on how to proceed is welcomed. Thanks
