Alright, I quickly putted in order your mapping related txt.files, and the mod launch a new playthrough, but crash right after. Do not touch anything else until you have beaten the crash. Here is the link.

Make a backup of it before trying something because you are almost there.
I had a similar problem once and reducing the size of a too big region with Geomod solved it instantly, but I might be wrong, it has been a while. Use only geomod to not confuse yourself with all the files individually until the crash is solved. Don't put a town on the sea, it's useless and potentially bad, I removed the black dot on the sea.
I think your problem is that you must put a new region rgb on all the ground type that aren't water, and possibly have a minimum of ten regions?
Try with geomod only, and when adding a region, do everything like it is said in the manual. Don't skip anything.
Now come on, fellows, he must not be far now, his mod launch a campaign and crash right after. The log has nothing useful but it is in the archive. Someone else around must know more than me on scratch mapping? Remember when you knew nothing and needed a point in the right direction?
