While loading images to LR 5 I received the following,
"Lightroom encountered an error when reading from its preview code and needs to quit.
Lightroom will attempt to fix this problem the next time it launches."
Every time I launch Lightroom I get this message. When I click OK, the program closes. Basically can't do anything.
You need to trash the preview cache. It’s in the main catalog folder.
Delete the folder with the ending Previews.lrdata
The default location for the Lightroom folder is normally Pictures/My Pictures if you did a standard installation.
Re-launch Lightroom after deleting the Previews folder.
N.B. do not touch files ending .lrcat
