i Have been using Lightroom 6 on my iMac since updating from Lightroom 5 about a year ago.
I access LR from an icon but today it did not work. The opening page of LR flashes once and then goes out.
I can access LR 5 from the LR icon in Launchpad.
when I go into LR 5 all my files are there but many thumbnails are blanked out. Presumably these are the ones that I have put into LR 6.
please can you help me to get back to where I was yesterday and access LR6 again from the icon on the dock.
Can you try to open Lightroom from your applications and check if that works?
Open Finder> go to Applications > Adobe Lightroom > Double click on Lightroom to open and check if that works.
Also, make sure that the program should be updated to version 6.4 : Keeping Lightroom Up-to-Date
Thank you you for your reply.
I Got it working late last night. What I did was reload Lightroom 6 including its seriel number. I'm at a loss to know why it had dropped out but reloading it worked.
Thank you again for your suggestions which I have kept on record.
