I have minecraft forge 3.3.8.153.
It has it's own modloader. I install that and everything is fine, until I put industrialcraft-2_client1.97.jar in the mods folder. I run minecraft after that, and it gets stuck on the mojang screen. Here is the forge log:
As you see, at the bottom, it says "initializing mod_IC2" and just stays there. Nothing happens after that. I don't know if this is forge or IC2, but I can install other mods just fine, so it must be IC2. I don't know if anyone else is having this issue, I couldn't find any other problems related to this one in the bug section in the forums.
Thanks,
