first i've look all the root files, they seemed perfect... tried to compile: ERROR at Texture03Texture.rsc
from this .zip you provided, one of the texture has a wrong size. Texture03.png is 1000x1000 instead of 1024x1024.
once i fixed that i ve been able to compile it, and then package it. i dont understand how you could compile it without error.
make sure you always always delete its Bin and Build folders that is creating each time you compile. why that ? to make sure your compiler have all the right info and not some old info coming from an old compiling tentative.
so i compiled it fine after resize, packaged it , placed the .pkm inside game/windata/ folder and launched the game for real. activated your mod, reloaded, and then i asked to build it, supplied the resources, and everything works fine !!
