All my LR previews are suddenly missing; thumbnails and library module. Previews only show in Develop module; thereafter the preview image is rebuilt, but only for that one image.
LR 6.1.1 (not CC), Mac 10.11.3. Working fine until latest import, when images imported but no previews built, and no other previews for previous images displayed. File names, tags, keywords and other data do show normally.
Updater does not show LR update available. Manual update to 6.5 does not work.
Ideas? Thank you very much!
First thing to do is turn off the option to use the graphics processor in the performance tab of the preferences.
See if that helps.
