"java.lang.VerifyError:" "registerCraftingRecipes signature" error, help!

    I decided to update my mod collection to 1.4.6, and some less important mods showed an error. I deleted them and then I came to IC2. It also showed it. What should I do?
    The error log is here.
    The mods are:

    • Steve's Carts
    • Railcraft
    • ComputerCraft (which also reports the error)
    • Buildcraft
    • Valve pipes
    • IC2
    • Redpower (all modules including compat)
    • Forestry

    Help?


    [EDIT]: Is this the right topic or should it be in "Installation"?

    If you let me play with your reactor, I'll give you one of my hand-made cookies ( :Resin: ).
    P.S. I'M A FRIKKIN NINJA ( :Nano Saber: ) MECHANIC ( :Wrench: )! DON'T MESS WITH ME BECAUSE I NOW HOW TO USE ADVANCED ( :Tin Can: ) TECHNOLOGY ( :Bronze Hoe: ).
    (DISCLAIMER: By hand-made I mean condensed out of cobblestone generated by my generators. Borka (Borka223, 223Borka) is not responsible for any booboos caused by the explosion of a nuclear reactor.)

    I see two problems in that error log: firstly, your Forestry jar is broken and needs re-downloading, and secondly, you're trying to use IC2 1.111 (for Minecraft 1.4.5) on Minecraft 1.4.6. You should use the 1.112 beta instead.
