Thank you for your reply.
With CodeChickenLib-1.7.10-1.1.3.134-dev in my forge/eclipse/mods folder, the game will launch just fine. However, when I add in any other mod, dev version or not, the game will still crash.
For simplicities sake I've been trying to get NotEnoughItems-1.7.10-1.0.4.95 working but dev or universal versions both crash the game very quickly on launch with the following error log;

It's worth nothing that ChickenBones' forum post links to CodeChikenLib, which it says is the new name for CodeChickenCore. The latest version of CCL (for 1.7.10) being CodeChickenLib-1.7.10-1.1.3.134-dev. However on his website for all the other downloads it's still called CodeChickenCore and the latest version is CodeChickenCore-1.7.10-1.0.5.37-dev.
I tried both with exactly the same results.
