Post this again this fall, when I take assembler.
Make sure you are using the right 1.17f for the particular editer. I stayed with the first 1.17f (the one with the army/leader goody huts).
Also, I suggest if that doesn't work, uninstall the game, then delete the civ3 folder. Then restart the computer and install again. Before you intall any patches, run the game, if it works, then install 1.16f (if you saved it). If it still works, then install 1.17f. If it works, then it must have been a currupt file. If not, then you'll to go back to the previous update (do as you did before).
That's all the tips I could give.
