          On rare occasions Lightroom doesn't shut down normally. When that happens there is a file left behind with the lock extension. It has the same name as your catalog, except for the extension. Look in the folder that contains your catalog and locate the lock file and delete it. Then you should be able to start Lightroom again.

            Hi Keithj,


            Please go to the location of the Lightroom Catalog, and please delete the file .LOCK

            Once done, please try and launch Lightroom and let me know if it opens or not.
