I have posted this as a comment on my original issue but figured that i should make a new one as the original has been closed.

Updated to the Direwolf20 1.3.0 version so as to be using the newer version of forge and added ee3 0.3.501 to it i am now suffering a new crash error.

Update Pneumaticcraft. That's the mod at fault here.

Thats done it, cheers
