Solved License Plate Mod Problems

SOLVED: EVERYTHING SHOULD HAVE THE SAME NAME


So, hello there.
I'm currently stuck with making my first mod. ( A licenseplate mod)
The problem is, whenever I wan't to change the name of the folder that's located in "licenseplates", i get a no texture error. ( And yes, I updated the paths in the .jbeam and .json file)

Those were the only strings to change when I want to rename the folder, where the licenseplate is located, right?

JSON file:

"backgroundImg" :"vehicles/common/licenseplates/user_license_plate/SA.png",

changed into:

"backgroundImg" :"vehicles/common/licenseplates/bih_sa/SA.png",

.JBEAM file:

"licenseplate_path" : "vehicles/common/licenseplates/user_license_plate/bih_sa_license_plate.json"

changed into:

"licenseplate_path" : "vehicles/common/licenseplates/bih_sa/bih_sa_license_plate.json"

and the mod just works fine, but not when I change the name of that one folder...
