Need help with a crash.

  • First: The link is non-existent.
    Second: Are you sure you're running IC, NOT IC2? If you're running IC2, post in the bugtracker: bt.industrial-craft.net
    If you are using IC (in which case you would be running MC 1.7.3beta), then I can't help you.

  • Are you sure you're running IC, NOT IC2? If you're running IC2, post in the bugtracker: bt.industrial-craft.net, If you have optifine installed and Multicire on, then thaz could be a reason.
