During my trial period I created a book. My photos is on an external drive, but the driver is not reading in Lightroom. All my photos is now marked with a red exclamation mark. How do I get my photos activated in the book so I can make changes & download the book to be printed?
Are the photos in a specific folder(s)?
Right-click (control-click) on the folder name in the Library and choose update folder location. Then navigate to the connected external drive to point LR to it. Click the following link and go to: Part 2 - Updating Folder Location
