JustEnoughIDs doesn't fix level.dat

[disastercube]

I have around 70 mods and before I changed the glider keybinding settings everything worked fine, seconds later the world crashed and every time I wanted to create a new world the "level.dat" error showed up. I saw a couple of issue of this saying that adding "justEnoughIDs" should work but unless I change the keybindings back to normal nothing works.
