Okay so I am trying to get the mod Not Enough Items to work...I got CodeChickenCore to work but as soon as I add NEI to the coremods folder, log in, and try to start a world itll load but then immediately go to the "Shutting down internal servers..." message and then crash, this is the crash report. Any idea why NEI won't work? (since it mentions CodeChickenCore I feel its the problem but it works fine without NEI...)

CCC is trying and failing to find NEI. I also notice that NEI isn't listed in the bottom System Details. Does NEI show up as successfully running in ForgeModLoader-client-0.log? – SevenSidedDie Apr 6 '13 at 22:48
Is NEI in the 'coremods' folder? – user48694 May 17 '13 at 19:00

Are you sure you installed the mods correctly?

Copied and pasted from the NEI MinecraftForums: "The process for installing NEI has changed. (For the easier AGAIN!).

Install FML OR MinecraftForge into the jar. Place the CodeChickenCore jar file into the coremods folder. Place the NEI jar file into the coremods folder. Place any modules' zip files in the mods folder."

Otherwise, I would guess NEI might be conflicting with another mod (You have a lot.) If I were you, I would try TooManyItems.

First thing, have you deleted your META INF folder? That folder stops mods from working altogether. If you have try to reinstall the mods and if that still doesn't work try deleting your .minecraft folder then log back on to minecraft and it'll update and give you a fresh folder. This happened to me before so try them 3. If you get confused tell me and I'll put a video up for it.

The question already says the mods were working before adding NEI, so it can't be a META-INF problem. – SevenSidedDie Apr 6 '13 at 22:52
