I got the following error when lauching Lightroom 5.7 "Lightroom encountered an error when reading from its preview cache and needs to quit."
Any suggestion to fix the error?
You need to delete the preview cache. LR will create a new one.
Here's how to find it: https://helpx.adobe.com/lightroom/kb/preference-file-locations-lightroom-41.html
Make sure to only delete the cache and do not touch any other files like *.lrcat.
