I have the individual (not CC) Lightroom 5.7.1, and plenty of space of my computer. At first I had no problems with the program....but now all I get is "not responding". This is so frustrating because I can't seem to find a answer to this issue, and I can't use a program that I paid $150.00 for.
What module are you in and what are you attempting when LR5 stops responding?
90% of the time it's the Develop module. I will just be editing and it's stops responding. It's so frustrating. I have to exit out, which can take a while too. And just this past week...it started going back to not responding as soon as I open it back up in the Library module.
