Yes, I have got the right version of forge and the right version of minecraft, I have been working with forge for over 3 months always installing it the same way with No problems at all, But now that I have tried to install the NEI mod( yes I did put them into coremods) It seems my minecraft just wont work, even when i just enter forge alone with no mods, I keep getting this dam error, Please I need help, Minecraft without mods is just plain vanilla which I have beaten too many times.

Ok, I have fixxed this problem a bit, I didn't remove the coremods from their folder,a nd once I did everything worked, But it seems I cannot enter any coremods so I can't use NEI, Any suggestions on what is going on? You can't believe my rage right now -.-

Are you using the latest version of NEI and CodeChickenCore?

Yes I am using the REAL and latest versions of codechicken and NEI.

Unless the latest versions are out-of-date or glitched.

Post your logs so we can see the error
