Reader loads and runs but CTD if I use Tools

Reader DC running on Win10v1809.

Selecting "Tools" (From the top line menu) crashes to desktop.  Selecting "More Tools" from the side bar CTD.  So does selecting File Properties or Profile Preferences.....all CTD.

I was using the Tools to add my digital Signature on Reader DC.  Until this week. 

Uninstalled and reinstalled several times with no change.
