Hellelujah!
I did a complete uninstall of 2017...restarted the computer...then a complete reinstall with BIAB & Real Drums on C:\ amd all RealTracks on another hard drive. (Which is actually what I had done initially.)
This time it works. I installed the 49 Bonus pak & all of the BIAB, Real Band and RealTrack updates and it works.
I thank all of those who helped with suggestions, advice and general moral support.
If you're stuck in a hole...it's nice to think that someone is at least calling out to you with suggestions as to how to find your way out.
To all of those people...I THANK YOU!!!!!.
Now back to making music.
