Custom Battle Maps not working

Hello all, I created myself a mod, called syracuse Total war on my labtop, and I installed it a year later on my new computer,and I had lost the first rtw, which had the program directory of "activision". I bought the game again, and this time its directory was "the creative assembly". My mod uses the mod switch command, and has all of its files with in it, and it worked on my labtop. But when I ported it to my new computer, and when I tried "custom battle", the map would start flooded with water, or it would put me on a map that wasn´t what I selected. Example= bridge map = numidian desert.

Do you all have any ideas?

The coordinates specified for the locations in descr_locations.txt probably point to tiles that are sea on the new map.
