Hey i need IC2 back in Big Dig because some mods arent working without it like The iron man suite thing and the Rockets. So i downloaded already IC2 for 1.5.2 and it seems to work but my server always says he needs a new Forge version to start. So can someone help me how to install Forge 7.8.1 for my Big Dig Server? its usual Server from the Technic Launcher site.
