Can anyone help. I have deleted the a.lock file and restarted but it still hasn't fixed the problem as every time I try and start the programme the a.lock file comes back and the programme sticks on the opening page and goes no further saying that it is not responding. I am working on windows 10 on a new surface computer.
Try resetting your preferences.
start Lightroom while holding the Shift + Option (Mac) or Shift + Alt keys (Win). If timed correctly, you’ll get a dialog asking if you want to Reset Lightroom’s Preferences or Start Normally. Choose Reset Preferences.
