Civ III is my favorite of the 50 odd games I have. I have many mods including Terrain, wonder splashes, (Don't forget... you HAVE to have 'The King' as an advisor ;) ). the problem I have is that I have added some units to the game and I am having problems. I added the Engineers to the game; but they don't build cities and I can't use the keyboard. I have to use the screen commands. Also I added the 'Special Ops Team'. The problem I have with them is as soon as I build one, the game crashes. What the fudge am I doin' wrong?

You might want to browse through the mod boards. You will probably find answers to your problems there :)

Make sure the folder name/ini file/unit name is all the same. ;)

or if you still cant do any of that you could reinstall the game
