HEY, I NEED SOME ASSISTANCE WITH THIS MOG HUNTER SCRIPT! (VX ACE)

I don't know why, but I can't get this script to work outside of the the Master Demo for MOG scripts. Whenever I go into a battle, nothing shows up. If I remove the graphics, it still tries to look for them. But when they are in there, nothing. I tried following the instructions, it seems really simple, but I don't know what I'm doing wrong. Hope I'm not being an incredible noob, I've been messing with it for a couple of hours now. I even tested it in a new project and got the same results.

Recently, something changed when I was testing the script and it doesn't even try to look for the graphics. I wish I knew what I was doing wrong.

The script is the 'Boss HP Meter' included in the master demo for MOG scripts;

Yeah, I have all the required images (took right from the demo). But, even when I remove them from graphics/system I'm not even getting an error anymore telling me that the graphics are missing. It's really weird, but wether or not they are in there, nothing shows up. The first time I tried it and I was missing a graphic, though, I got an error. But since then, nothing.

And yeah, I put that <Boss Meter HP> along with the other ones in the notes of an monster (Hide HP, and what level the boss is) just to see if it was perhaps that they all needed to be there. It's like the script just isn't function for some reason. Even in a new project it just does nothing no matter what I do.

Did it work for you? I can record a video of myself going through the process and link it here just in case I'm making some kind of error. But I don't think I'm missing anything :S
