Homestuck.XYZ 2.0

I've been trying to use this modsuite all day, but I'm having difficulty understanding why the run wizard continuously returns errors claiming that characters are not properly defined. I'm not sure why this is happening or what I have to do to correct it. I've included some screenshots in the hopes of receiving assistance.
Please help!

There were some major changes made to refocus the project around exporting standalone projects, and I need to go back and redo most of the demo routes, unfortunately. My best suggestion right now is to look at the sbb demo.

Thanks for finally getting back to me! I've managed to finagle it at least somewhat into a coherent fansim, but I still have to learn a bit more coding than I expected to. Still, I appreciate you taking the time to give me some advice.
