New map problems

[DutchHistoryFan]

I am making a mod with a completely new map, however, everytime i start the game, it crashes (at the 'loading databases' part).

I already added all maps and other things in the 'maps' folder and they are copied and changed a bit from the original ck2 files so I don't know what it could be.

Maybe someone could now what the problem is or send some checklist?

All the files are in the .zip.

I would try adding your one land province's file in history/provinces.

I already tried that out before posting this threat..
