Code Chicken Core

So recently i got a server to play direwolf 20 for minecraft 1.7.10 with a friend but whenever me or my friend tries to load the mod pack we get this error. The same error comes up when i try to launch the server.

I have tried other suggestions like changing the graphics and other stuff but it happens to any mod pack with nei and code chicken core on. Any suggestions would be greatly appreciated.
