It worked fine with v13, that's the last one I tried. It's a shame no one's really taken over that script, since ray seems to have abandoned updating it. I'm kind of busy with gen 6 and some other things, so I don't really want to add more to my todo list. Maybe when gen 6 is complete.
You could test it out with that. If you're getting the same error, maybe you copied something incorrectly or something
