When you import an Elements Organizer catalog into Lightroom, the Upgrade Photoshop Elements Catalog option is missing, or an error occurs.
Error examples include:
If the images you have imported into your Elements Organizer catalog are stored on a network location, Lightroom 3 doesn't recognize them.
Lightroom looks at the Elements Organizer Preference file for information about converted catalogs. This file is created when Elements Organizer is launched. If you are transferring Elements Organizer from one machine to another, it's possible that the Preference file didn't transfer.
If the Preferences file contains incorrect information, it is possible Lightroom can't recognize existing catalogs.
Important: Apple made the user library folder hidden by default with the release of Mac OS X 10.7. If you require access to files in the hidden library folder to perform Adobe-related troubleshooting, see How to access hidden user library files.
If the problem recurs after you re-create the application preferences file, the problem isn't related to the preferences file. To restore custom settings, drag the file you moved in step 3 back to its original location. Click Yes to replace the new preferences file.
