After updating from CC to new 2014 updates Lightroom would not go from 'Library' to 'Develop' - develop screen was greyed out showing the message 'Develop module is disabled. Please renew your membership to reactivate the Develop module.' Since my membership is fully up to date. I then uninstalled Lightroom 5 and then installed it again. Now when I try to open Lightroom 5 its LOGO flashes onto the screen and then 'crashes' in an instant. Please fix.
