12-25-2019: **RESOLUTION** After using the Download method, rather than the CD, to reinstall TT on my computer via InstallTurboTax.com, the app opened OK and has been working OK ever since. My lesson learned is using the Download method, rather than the CD, gives one a better chance of receiving an app that is not corrupted. After all the frustration, my opinion is TurboTax is still the best tax preparation software available for the majority of consumers.
