I can´t launch my copy of Lightroom, When I try to start it up, it says that the LR catalog is already open, but it´s not. What can I do here???
Using your computer's operating system (Explorer or Finder), go to the folder containing the LR catalog.
There will be a file with the extension .lock.
Delete this file. Do not delete anything else.
The catalog should now open.
Awesome thank you
