Crash on placing torch

    Hi,


    Been trying to get IC to run lately, but it seemingly crashes every time i place a torch.


    This is the error i get from the server.
    [SEVERE] Unexpected exception
    java.lang.NoSuchMethodError: dj.isBlockSolidOnSide(IIII)Z

    I suppose i get the very same error when i try singleplayer and place a torch.
    I have been using completely clean installs of MC and MC_Server and using no other mods. Also I have tried to make it work across three other computers...
    So, now i'm stumped and need support =/
    The IC version i've used is 8.55_02
