Unable to repair DB

[lyndondrake]

Hi, I have a problem resulting from a MacOS crash. I get the following message:

If I click Repair, I get this:

and this Log window:

When I check that group, the file is indeed missing. What can I do to at least get rid of the error message every time I open that DB?

Control-click the entry and choose Reveal or Move to Trash.
If you select the latter, you will need to empty the Trash to purge the reference.
