Minecraft Forums

Hi guys

My apologies if this is the wrong section.

trying to install mods for my son, i have installed Toomanyitems n works no problem. I cannot seem to get any other mod to work.

Trying to install Lucky Block mod at the moment, keep getting this report.

I get basically the same error report for each mod.

A detailed walkthrough of the error, its code path and all known details is as follows:
