Try to re-create the problem

After you have removed your existing preferences, restart Dreamweaver. The application creates new preferences files, folders, and registry entries, as applicable, using the default settings. 

Then try to re-create the problem that you had before.

If the problem was resolved, then damaged preferences was the cause.

If the problem persists, then the preferences are not the cause and you can replace the original preferences.

To replace the original preferences:

  1. Quit Dreamweaver.
  2. Delete the new preferences folder and restore the original name of the previous folder.
  3. Do one of the following:

    • Mac OS: Delete the new preferences file and restore the original name of the previous preferences file.
    • Windows: Double-click the registry backup file you created.
