Typically I thought if you relink one, it's smart enough to find the rest if it finds the same names in the new directory?
No. It didn't. In fact, all the names were GONE! Thanks God I had the files on another machine with the older version software to refer to. I had to relinked each file one at a time. So happy I got it back! Now I can attempt to add a run cycle to my project.
BTW: here is the end result of my very first Character Animator/After Effects animation.
