Navigation Pane Doesn't Work

Question

For some reason, the Navigation Pane in my MS Word doesn't work.  I usually use the toggle from my quick access toolbar to toggle it on and off.  It worked fine last night.  This morning, I open the document and I hit Ctrl F to see the Navigation
Pane, but MS Word didn't respond.  I tried to toggle in the quick access toolbar and there was no response.  I went to the View and I tried the Navigation Pane toggle, but there was nothing.  Anyone know how I can bring the Navigation Pane back?

Hi David,
Please also try deleting the Word Data registry subkey to see if the problem was caused by a damaged Word Data registry key.
Note When you delete the Word Data registry subkey, Word resets several options to their default settings. For example, Word resets the "most recently used file" list on the
File menu. Also, Word resets many settings that you customize in the
Options dialog box.
1. Exit all Office programs.
2. In Windows 8 or Windows 8.1, swipe in from the right edge of the screen, and then tap
Search. (If you're using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and then click Search.) Type
regedit in the search box, tap or click Apps, and then tap or click
Run.
Or, in Windows 7, Windows Vista or Windows XP, click Start, click
Run, type regedit, and then click OK.
3. Locate the following registry subkey, as appropriate for the version of Word that you are running:
Word 2013
HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Word\Data
Word 2010
HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Word\Data
Word 2007
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Word\Data
Word 2003
HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Word\Data
4. Click Data, and then click Export on the
File menu.
5. Name the file Wddata.reg, and then save the file to the desktop.
6. On the Edit menu, click Delete, and then click
Yes.
7. Exit Registry Editor.
8. Start Word.
Please let me know the result.
