When I open LR5, I get an error that states, ?:0: attempt to index a nil value and can not open my library; how can I correct this?
Thank you in advance...
Please make sure that you have the latest update of Lightroom, that is Lightroom 5.7.1
Try renaming the presets folder.
Go to Preferences >> Presets tab and click "Show Lightroom Presets Folder"
Rename the "Lightroom" presets folder to "Lightroom-old"
Quit and then relaunch LR.
You may have to find your catalog manually under:
File >> Open Recent
