I currently store my photos/videos on a NAS, and had Elements catalog that hard drive (28,000 photos/videso), and backed up the catalog to an external hard drive. We've now moved and have a different internet provider, which assigned a different IP address to my NAS and the thumbnails to all my items now indicate a broken link.. Elements now thinks the NAS drive is "offline", even though it's right there (same file structure). Also, the reconnect drive option does not give me the new drive as an option, even though I can browse there just fine using Windows Explorer. Currently using Windows 8. any suggestions? I tried to restore my previous catalog using the version backed up to the external hard drive (onto the existing one), but nothing seems to have changed.
File structure is quite extensive (2014/January/event), so going to each file individually would be a big hassle.
What is your primary program Photoshop Elements 12 or Premiere Elements 12? Each is a standalone program with its own Elements Organizer 12. But when they are both on the same computer, they share the Elements Organizer 12 catalog.
Because of the NAS nature of your question, if it can be answered in a user to user forum, the best place may be in the Adobe Photoshop Elements Forum.
I have seen one attempt to answer that type of question.
The Adobe document on moving the Elements Organizer catalog does not get into NAS and the type of situation that you are in.
Please let us know your program and the outcome.
