Thank you. 

I have all the files the drawing is "looking" for but as I am learning, AutoCAD cannot stand any change in where a file is located or what connection may already be in place.  I must have moved or changed something, though I don't know for sure what.    I believe my problem lies in there, but am not certain.

To not waste anymore time I took the advice from another posting with a similar issue and simply started over.   I used a fresh sheet and brought everything in in the usual manner. All is well.  I had to reset the paper space drawings but it was not the end of the world.

Autocad always me to go to the brink of disaster, and my patience, but I always manage to find just enough smarts to save myself.  With this forum's help as well of course!
