As far as I know there is nothing in the new version of the mod that would cause problems with a saved game. You could try clearing the Civ 5 cache. That's a good cure all for Civ 5 mod problems.

Clear the Civ 5 cache:
1. Make sure you exit Civ 5.
2. Find the Civ 5 cache folder. It's location might vary slightly depending on what operating system you have. Mine is located at: "Documents\My Games\Sid Meier's Civilization 5\cache".
3. Delete the cache folder.
4. Restart Civ 5 and load the mod in the usual fashion. Civ 5 will automatically recreate the cache when the game starts
