I don't know if anyone else is getting an error with NEI install, but if I disable it via Magic Launcher, Minecraft doesn't crash. Error report in the spoiler

Any advice? And yes Code Chicken Core is installed in the Mods folder, it just isn't launching for some reason. And I only get this when I have NEI installed. This is probably a forge bug, but any advice would be nice. Thanks.
EDIT: I figured it out. IF people are having the same problem, just run NEI before forge, that will fix it.
