1.07f iirc is vanilla civ 3. I don't recall, if CAII can load them or not. I would think so, but not sure. If the game of civ you are running is 1.07F, then save create by later versions or other versions of civ will not be compatible. The last patch for vanilla is 1.29f. If you are running the conquest version of civ, it can load the vanilla save as long as they are at patch 1.29f. Conquest saves (aka C3C) cannot be loaded by vanilla, regardless of the patch level. The last patch for c3c is 1.22. Been a while, so I could have some things, wrong. If so, others will give corrections.
