To make the mod playable listen to what is said and play on the Event Horizon 1.13.0 version like instructed and kidnap the game's developer from his grave to fix the issues and errors he introduced in the 1.13.1 version of the game which is making the mod unplayable on said version instead of bitching on the mod developer.
