I bought lightroom in October 2014 before I joined Creative Cloud and do not need a membership in Creative Cloud to use. Now I get the message that my develop module is disabled when I try to edit. What is the fix for this? I am unable to use my Lightroom application. I discontinued my Creative Cloud membership December 22, but that should not affect my use of Lightroom which I bought prior to my membership.
Did you followed the steps mentioned in the Solution mentioned in Lightroom 5.5 "Develop Module Disabled, please renew your membership" where you posted the same query?
Also, Please try the solution mentioned in this help article Lightroom doesn't launch or closes automatically after splash screen
Let us know if that helps
