ok, but if I don't use it I get a white screen at the Mojang logo nevermind, it does it with an older version of forge. I updated and it fixed it. I downgraded because IC2 told me it couldn't find that same class. It's just a big error on my part

You don't need modloader with the latest versions of forge

Ok, I get this error not when I start MC but when I generate a new world: I'm guessing its a forge error because of the No such method error part.
