Okay....what I did was load up my last Final Save game I had, which dates back to before I installed ToSC. I did not 'convert this saved game' because I don't know how....how?
I shall also try the tactic of starting a brand-spankin' new game and see if that works. Thanks!
.....But if anybody else comes up with any bright ideas, let me know.
