General Solutions
1) Go to Help > Check for Updates.
1) Close Lightroom.
2) In the Back Up Catalog window, make sure the two functions
below are selected.
Two Selections
3) Click Backup.
4) If that doesn't help, shut down your computer, restart it,
and open Lightroom.
If you're using a Windows computer, the anti-virus software
may create a problem with Lightroom.
Try disabling your anti-virus software.
If this solves the problem, exclude the Lightroom folder
located in My Pictures or Pictures from the anti-virus software.
You may also have to exclude the folder containing the
photograph files that are in Lightroom.
1) Go to File > New Catalog.
2) Import a few photographs into the new catalog, and test various
functions.
3) If the new catalog functions properly, then the problem is
a corrupted catalog.
Do the following.
1) Close Lightroom.
2) Go to My Pictures or Pictures > Lightroom, and rename Lightroom
3 Catalog.lrcat.
For example, rename it as Lightroom 3 Catalog_bad.lrcat.
3) Go to where your backup of the catalog is located, select
it, and copy it (Ctrl + c).
By default, the backup of your Lightroom catalog is located at
My Pictures or Pictures > Lightroom > Backups.
You may have changed the default so that you're backing up to
an external hard drive.
4) Go to My Pictures or Pictures > Lightroom, and paste it (Ctrl
+ v).
5) Double click the file to open Lightroom.
A preset may have become corrupted.
Or, did you recently create, or download, a preset?
If so, the new preset may be causing the problem.
1) Close Lightroom.
2) Locate the Presets folder.
The folder is either in the default location, or it is stored
with the Lightroom catalog if you selected that option.
Go to
Change
a Preset Preference.
3) Rename the Presets folder.
For example, append _qwerty to its name.
Append _qwerty
4) Restart Lightroom.
If the problem is now solved, do the following.
1) Close Lightroom.
2) Go to the location of the Presets_qwerty folder.
3) Lightroom probably created a new Presets folder.
Make sure its empty, and delete it.
New Develop Presets Folder
4) Rename Presets_qwerty back to Presets.
5) Delete the new preset.
6) Open Lightroom.
The preferences file may create problems with Lightroom.
Because you'll have to redo your preferences, you may want to
record what they are.
Go to:
• Edit > Preferences (Windows) or Lightroom > Preferences (Mac).
Or, press Ctrl + ,.
• Edit > Catalog Settings (Windows) or Lightroom > Catalog Settings
(Mac).
Or, press Ctrl + Alt + ,.
Then, do the following.
1) Close Lightroom.
2) Navigate to the preferences file.
If you can't find the folders below on your computer, go to
Hidden Files & Folders.
XP: C: > Documents
and Settings > [username] > Application Data > Adobe > Lightroom
> Preferences > Lightroom Preferences.agprefs
Vista: C: > Users
> username > AppData > Roaming > Adobe > Lightroom > Preferences
> Lightroom Preferences.agprefs
Windows 7: C: > Users
> username > AppData > Roaming > Adobe > Lightroom > Preferences
> Lightroom Preferences.agprefs
Mac: Library > Preferences
> com.adobe.Lightroom.plist
3) Rename the preferences file.
For example, append _old to its name.
4) Restart Lightroom.
If the problem is now solved, delete the renamed preferences
file, if you wish.
If the problem isn't solved, delete the new preferences file,
and rename the old one back to its original name.
Specific Solutions
Lightroom creates a "lock" file when it opens.
Lightroom 3 Catalog.lrcat.lock
When the program closes, the lock file is deleted.
If Lightroom, or your computer crash, the lock file may
still be present, preventing Lightroom from opening.
If Lightroom or your computer crashed, and Lightroom won't
open, do the following to check for the lock file.
1) Go to My Pictures or Pictures > Lightroom.
2) Delete Lightroom 3 Catalog.lrcat.lock.
Make sure you delete the lock file, not your catalog!
If you're using Photoshop or Photoshop Elements, make sure
you're using the latest version of the Adobe Raw Converter
that's compatible with your version of Photoshop/Photoshop
Elements.
Go to
Adobe Updates.
Your print driver may have become corrupted, or may be
out-of-date.
Go to the website of your printer manufacturer and download
the print driver or an updated version.
If Lightroom is still acting out, go to
Resources.
