Minecraft Modded, any world I try to create or load just won`t.

[Snowiimountain]

For some reason The modpack Im trying to play won`t load any worlds I want to make and its annoying.

it not crashing or anything like that, just the "Loading World" that shows anytime you try to load a save won`t disappeared and it won`t load and I don`t know what to do anymore.
