Develop module, Map module, and Edit In stop working

Issue: The Develop or Map module, or Edit In, stop working.

Solution: Reestablish your membership.

In Lightroom 5.5 and later, when your Creative Cloud or other membership expires, you continue to have access to the Import, Export, Library, Book, Slideshow, Print, and Web modules. However, until you reestablish your membership, you won't have access to the Develop or Map modules, or the Edit In functionality.
