There was a fatal error starting up minecraft and FML

[dfrankcom]

I am using Magic Launcher to install and use mods as I find it very simple to operate. It has worked supremely up until this point, when I tried to use Forge. I have read countless forums, but can't seem to find an answer. I have put Forge in the launcher by itself, and with Modloader, but neither work. I have also both deleted and manually installed the contents of the .minecraft/lib folder. I am using the newest version of forge too. I am now completely at a loss, and this is the only place that I could think to turn. My log is as follows:

Any advice would be greatly appreciated.

Thanks,

Ensure that you have installed EVERYTHING in the forge/fml zip into your minecraft.jar.

I did some fiddling after posting my response, and did some more research, and I finally solved the problem. I just had to delete the "coremods" folder in the .minecraft directory. I hope this helps anyone else that had the same problem as me!

You probably had NEI installed but not CodeChickenCore
