Title: Tekkit Client Crash after attempting to add ChickenChunks

Version: 3.1.2

OS: Windows 7 Home Premium 64bit

Java Version: Java version 7 Update 6

Description of Problem:

I wanted to add Chicken Bones' mod ChickenChunks to my personal tekkit server, now the server runs without any error, but I couldn't find the chunkloader the mod adds, so I thought I needed to add the mod to the tekkit client as well, however it causes minecraft to crash instantly after the main screen loads.
