    Moved to IC2.


    Also, looks to me its Forge problem, are you sure you have the right version of Forge?


    http://www.mod-buildcraft.com/


    BuildCraft is having problems with the recommended build of Forge, you might try a different version.

    Lesson 1: Watch over your crops....

    Actually that's an old post on the buildcraft site, the recommended version works fine, as does the latest version.


    Tho the version that OP is using was never compatible with IC2.


    Re download forge and you should be fine.
