Unable to import a travel catalog into the master catalog

[cwog001]

I have a main LR Catalog and a small catalog created when travelling.

Using the File - Import from another catalog I get the Import from Catalog "17 nw spain-2 panel

however the checkbox next to the All Folders (16 folders) line has a "-" sign and all the other check boxes for the folders are blank and checkboxes for each folder cannot be set to any value apart from blank.

When I select Import i get the following message.

An internal error has occurred

Database "/Volumes/Main3 /lightroom/Lightroom/Lightroom Catalog-2 ircat": UNIQUE constraint failed:

AgLibraryFolder.id_local

Statement: INSERT INTO AgtLibraryFolder(id-local,id_glbal, pathFromRoot, rootFolder)

VALUES(?,?,?,?); (error code 19)

I have imported the catalog into a different catalog with no visible problem.

What do I have to do to fix this - or does the 17 nw sopain-2 catalog have to remain an orphan out in the cold from the main catalog.

Thanks for any help

Hi cwog,

We're really sorry for all the hassle. Could you please try resetting the Lightroom preferences back to defaults and let us know if that helps.
