Superheroes Unlimited and Legends Core

I've downloaded Superheroes Unlimited mod into my server, And when I click start it says starting and automatically says stopping and stops the server.

I've went into the log and suggestions showed " Download legends mod because it is needed for Superheroes Unlimited ".

But there is no core/mod named legends in the mods list.

Also this is the log:

Ok just saw that Legends core can't be added because it's not in curse but shouldn't they remove Superheroes Unlimited too?

Or is there another way of playing SU in the server?

Well, Thanks I guess.
