UPDATE: After extensive checking, I narrowed the issue to Windows, because I was unable to utilize the "speech recognition" and "set up microphone." I kept getting an error message when I clicked on those two functions that told me that the "wizard could not start" (see image capture below). So, I decided to REVERT BACK to the previous version of Windows. It was easily accomplished and immediately after "going back" to the previous version, ALL the problems vanished! Speech recognition worked. Set up the microphone worked! and VOICE ATTACK worked!
Thus, the update of Windows to version 1803 is apparently in conflict with my computer. Hopefully, I can learn more, soon. But, for now, I am, again, fully operational with Voice Attack.
