Edit the artwork on spartan ui

[jealei]

HI, on currently trying to edit the artwork for the addon spartan ui so i can use a square minimap instead of the round one, but i ran onto a problem.
I found the file with the minimap artwork, but when i log onto the game it dosen't look right

this is how i want it to look


but this is how it ends up looking


does anyone know what file i have to edit to make it right?
