I was using Lightroom, downloading images and the power went out. Going back in I get a message Lightroom encountered an error when reading from its preview cache ad needs to quit. Lightroom will attemot to fix the problem the next times it launches. Select OK and the program closes. I hae done this many times as well as unistall and reinstall and the same message comes up. I need help as I need to edit pictures by tomorrow. Thank you Jake Irsik email@example.com
Please delete the Preview Cache.
To delete the preview cache, do this:
1. Quit Lightroom.
2. In your Operating System, locate your Lightroom catalog. Typically catalogs are in /Pictures/Lightroom on Mac and My Pictures\Lightroom on Windows.
3. Find the folder whose name ends with "Previews.lrdata" and delete it.
Hope that helps
