Thanks very much for that.
I think the script that's causing it is Book+ComicsFilenameDB.js.
If you edit that script in a text editor, and locate line 78, it should look like this currently:
cmd.type = (typeof column.type === 'undefined') ? null : column.type;
Please try changing it to:
if (typeof column.type != 'undefined') cmd.type = column.type;
If you make that change and then rename your Script Addins folder back to its original name I think that should get you up and running again.
We'll add extra safety checks to the next Opus update to prevent a crash in this situation.
