I had successfully installed and been using LR6. Today it would "freeze up" when I click "open this catalog" for ANY of my catalogs. Please help!
Could you please check and make sure that Lightroom is updated to the most recent version : Lightroom 6.4 : Keeping Lightroom Up-to-Date
Also which operating system are you working on , Windows or MAC ?
I am operating on a Mac, and I have LR 6.0. I will see if I can do the update. Thanks.
Yes, I would suggest to update Lightroom first and then check and let me know if it helps or still the same issue.
