Pre Made Map + Additional Civs DLL?

I have downloaded a mod and downloaded a dll that modified the number of civilisations allowed to 50+. Everything is working, however I have also downloaded a premade map which works on the original Civ IV BTS and crashes to the desktop on the mod. I assume that this crashing is because of the different dll, if so, is there any way to make the map compatible with it?

See this thread: Modding maps with a text editor

Specifically, the section in the first post that starts with "Maps with more than 18 civilizations/making maps compatible".
