You're using a developer version of Forge Multipart, this only works in the development environment. Download the universal version instead.

java.lang.IllegalArgumentException: Failed to register dimension for id 2, One is already registered

at net.minecraftforge.common.DimensionManager.registerDimension(DimensionManager.java:118)

at hu.hundevelopers.elysium.Elysium.init(Elysium.java:879)

 

The Elysium and another mod are both configured to use dimension ID 2. You need to change this in the config files of The Elysium or the other mod (assuming they've added a config option for the ID).
