  • sorry i cant provide a full report but the screenshot is all i have. reason being it would appear for a few seconds and then disappear.if you have a fix or file for me please let me know

  • Go to your .minecraft directory and copy the contents of your modloader.txt (preferably in spoiler tags).

    Anyway, it seems something is trying to use IWrenchable (part of the IC2 api that allows wrenches to interact with machines, I think) before IC2 is loaded. The modloader.txt should say what mod is causing it.

  • Either you messed up installation by extracting the jar file or you grabbed a corrupted download.
    Try redownloading the file and make sure you do NOT extract the jar, it's meant to go into the mod folder as whole.
