    Lightroom 2015.4 encountered an error when reading from its preview cache and needs to quit.


      I did an update on Lightroom CC 2015 and now Lightroom won't launch. Photoshop will not open .jpeg files, says it can't find them. It will only open PS documents.


      I tried to delete the LR 5 Master Photos Catalog Previews.Irdata file but that didn't help.


      I'm using Mac OS X 10.9.5, not sure if I need to upgrade my system to Sierra instead?


      Any ideas?


      Thank you!
