There appears to be an issue with the story format itself, it has a little exclamation mark triangle next to it in the format list. I try to delete it so I can re-install it, but it won't delete. Also, I tried renaming the version variable in the format's .js file so that it treats it as aa separate version and allows it to install, but it just ends up loading forever when I try to install it.
Fully willing to believe this is my computer's specific issues though as there's all kinds of permission nonsense that is outside of my control.
Thanks for your help, anyway. I'll figure out a workaround I suppose.
