I've tried installing Not Enough Items, and I get stuck on the "building terrain" when loading up any world, when I try to log onto a server, it loads, and then stops and displays the dirt background, and then it shows the crash screen.

I've made sure to Force Update, make sure I have all of the latest versions, and I've followed the instructions perfectly.

I've done this 3 or 4 times now.

Any Help?

If I take NEI out of the coremods folder, minecraft works just fine.

Have you deleted the META_INF folder?

Like I said, I followed the instructions exactly.

Step by step.

100%

Try magic launcher. It makes it really easy, I mean really easy to install mods.

Here is the forum page for it

It shows on the page how to install mods.

Thanks, I tried installing it, works fine except for it is still stuck on the same "Building Terrain" screen.

When I'm looking at the "Setup" tab in the Magic Launcher, it doesn't say `OK` like the rest, it says `internal mod`

Hmm.....Im installing this myself, and in Magic Launcher it says Forge...1 errors (but works fine, no crashes so far playing), then says codechickencore or whatever the name is OK, then it says NEI-OK.

I'm not sure, I'm going to bed soon, but i'll try to get it working.

Answer these so i can assist further

1: What version of Forge because some versions of the CCC are not compatible with some builds of Forge.

2: Is your Code Chicken Core mod installed <== This is severely important.

3: what version is your NEIs Mod.

4: Is the CCC mod and NEIs mod paired correctly. certain versions of NEIs are meant to use specific versions of the core mod.

5: Have you considered using MultiMC Launcher instead of Magic Launcher.

That or you can use sk89q's launcher

I highly recommend MultiMC because it also provides a cute sexy layout for error reports and even supports posting to pastebin. Also in the event MC crashes the launcher to MultiMC can force it to close without closing the launcher.
