I have been using Lightroom 5 no problems since 2014 and just uploaded my latest series of images and hit DEVELOP to go edit them, and it is now saying develop is disabled and i need to update my membership......i went to the LR5 logo top left of screen and saw i was not signed in, went to hit sign in and it came up that i was not connected to the internet and would not let me sign in further - Does anyone have any advice on how to fix this and get back my editing ability, i can still import and export but cannot edit?
You do have a limited credit of activations only. To activate, you need the code you got once you bought LR5 and need an internet connection during that process. If it was an upgrade to an earlier version, you'll also need this code to authorize the upgrade.
Yes, @Per Berntsen , your memory is correct, there was no license activation (requiring internet) used in Lr 5, you just typed in your serial number and the software determined if it was valid, and from then on you should be good. No further activation would be needed. So the fact that some sort of license activiation is now apparently causing problems, I feel that the problem is the Creative Cloud application, as I explained elsewhere in this thread.
Develop disabled usually happens when you install the Adobe Creative Cloud application on your computer (perhaps because you use other Adobe software that is newer and part of the Creative Cloud, or you installed a trial version of Creative Cloud software and then deleted the software but not the Creative Cloud application).
You need to un-install the Creative Cloud application, then run the Creative Cloud cleaner tool, and then try LR5 (you may need to re-install LR5, I don't know).
Another thought along those lines is that you downloaded a newer version of Lightroom Classic as a trial, and that is what you are trying to open now (not Lr 5) after the trial has expired.
