No, it didn't work with version 54.

Guys, just to test, I took all the maps out of the Maps folder and installed the mod correctly. I checked it several times! It doesn't work; it gives this message and that's it. There's something wrong with this version of the mod because version 54 worked perfectly! Try to find the error because I don't know what it is. All the mods that were installed before and worked with version 54 are still installed! If you have any ideas, let me know; maybe it will help!
