Adobe Photoshop Lightroom 1.0 and 1.1 stores data about your photos in a catalog file. If your catalog file's structure has been compromised, one of these error messages can appear:
- The catalog "[Catalog Name].lrdb" appears to be corrupt and cannot be used.
- The catalog "[Catalog Name].lrcat" appears to be corrupt and cannot be upgraded.
It's possible that some of its data is no longer accessible.
Before Photoshop Lightroom 1.1 was released, a data corruption issue was fixed in SQLite, the third-party database implementation used in Photoshop Lightroom. Changes to Photoshop Lightroom 1.1 make it less vulnerable to this and other corruption problems.
