For some reason, I followed the directions for downloading the mod, even using the auto-installer for it, and when I go to see if it works, it gives me this.

When I tried forge without mods, it works, but with mods, it crashes. Can anyone help me in any way?

Bump, I'm having the exact same issue.

Thanks to the mod author for fixing this for me!!!
