    I get this error message when I attempt to open my usual catalog; a new catalog opens OK. The problem began after a spontaneous reboot (never happened before or since) when Lightroom was loading. Re-starting the computer doesn't help. How can I unlock the catalog?

    Windows Vista 64, Lightroom 2. 4GB RAMM, 2.6 GHz quad core processor, plenty of hard drive space.

    Try looking into whatever directory your catalog is in and deleting the ".lock" file with the same name as your catalog.

    Thank you, I had the same problem.

     

    But honestly Adobe… is it too damn complex to search for another lightroom process instead of asking the user to close a non existant process? If you don't find the process you can easily assume something crappy happened and delete the lock file by yourselves and then check the integrity of the database.

     

    I mean… shouldn't be that complex right?

    I can not tell you how many times LightRoom 3.5 or earlier just freezes under Win 7-64 bit. You can  not CTL+ANT+DEL or anything else but manual shut down. This typically occurs when user enters something before a LightRoom task is completed. It is not acceptable!

     

    When rebooting, anything might have happened but usually nothing. I failed to notice a lost folder of all 2011 photos. This occurred just after my last backup so some delay before even noticing since I was working on older folders. So all are now gone.

     

    The most recent freeze was the typical several minute wait while loading the catalog and reading the camera's card. The inevitable reboot left the catalog locked so it was easy to simply delete the lock file after nearly an hour getting to this suggestion. Maybe we are using oppisite sides of the brain but the delete lock file suggestion would help on the actual error message. The real problem is frequent lock ups! Do you think enough 64 bit users might dump this product with similar lock ups / lost files or folders and long research time to find a solution? Release 4 is not looking likely!LightRoom warning.JPG

    Thank you!   Worked like a charm.  I only encountered this error today for the first time after working with LR since release of version 1, and that was due to a sudden power outage.  Glad that finding the solution was this easy!

    oh no,  i just did as suggested above. Great lightroom opens but all the grading i did on the pictures have gone! I even made a copy of the LRCAT file before deleting the lock file and LR was def closed as i just did a restart.

     

    What happened to all the work i just finished? can i get it back. deadline 29 hours...

    thanks.
