The problem is that the way it downloaded seems to be version specific. And it's getting specific data value issues. I believe it mentioned something about the value needing to be set to 2 or above.
Anyways we'll if spyderrock is a good addon creator who actually updates his addons to work. Or if he's just a one-hit wonder. This is coming from a long time subscriber of his YouTube channel as well.
How to fix?
