Mac Screenwriter 6.7 preferences error, "WBPreferenceFile.cpp", root node failed

If you get a crash in Mac Screenwriter 6.7 that says something like, 'root node failed in WBPreferenceFile.cpp at line #454’, the problem is that the Screenwriter preference file has been damaged.  This sometimes happens if it is left over from an earlier version and was not updated to work with the current version of Screenwriter.

The solution is to delete the Screenwriter preference folder called, "com.writebros.Screenwriter67".  Here are the steps to do it.

1. Quit Screenwriter if it is running
2. Go to the Finder by clicking on the desktop
3. Select the GO > Go to Folder command (or SHIFT+CMD+G).  Enter the following (or copy and paste it):
   
   ~/Library/Application Support
   
   You'll see the path change to your own home user path.  PRESS RETURN.
4. Right-click on the "com.writebros.Screenwriter67" folder and choose the Move to Trash option
5. Relaunch Screenwriter
6. You will get a notice that this is the first time you've run Screenwriter and it needs access to your folders
   
7. Click OK
8. It should open a window that is your documents window titled, "Movie Magic Screenwriter"
   
   
9. Press Confirm
10. You may get a notice or two -- press OK
11. Screenwriter should open for you
12. Test it by typing a word or two and use the File>Save menu command to save your document
13. Screenwriter should save the file successfully and it also creates a new preference file so the problem should not happen again
