I'm having trouble getting my Minecraft to launch which is modded.

Here's all the mods I have:

Here's the game output:

Lois: Together we can do anything: face any foe, overcome any obstacle.
Peter: Yeah, climb any mountain, rent any video, dial any phone. And not just our phone, Lois, other people's phones. Decent phones, God-fearing phones, phones that everybody else gave up on, but we knew better because we were a team!
Brian: What the hell are you talking about?

You have a 1.7.2 version of Chocolate Quest and a 1.8 version of NotEnoughItems. You should get their 1.7.10 version.
NotEnoughItems also need CodeChickenCore to load. Download CodeChickenCore and delete CodeChickenLib.

Ah I see now. Thank you! This helped a lot. I can't believe I didn't realize that.
