I think the guys at MinecraftForums are better at answering mod-related questions than we here at EightForums are.
Have you tried doing a clean install of Minecraft and removing any other mods installed?
You could also try downloading th of newest version of Java.

as of 1.5.1 they're built in. you just have to make sure you allow cheats under the world options at creation
