    Go to your .minecraft directory and copy the contents of your modloader.txt (preferably in spoiler tags).

    Anyway, it seems something is trying to use IWrenchable (part of the IC2 api that allows wrenches to interact with machines, I think) before IC2 is loaded. The modloader.txt should say what mod is causing it.
