SMP Worlds not loading

[Ehnderzz]

Hi.

I'm very new at modding, but I've been trying to code my own mod and I've been having troubles.

Anyways, I finally got Minecraft to load, and recognize the mod, but my Single player worlds wont load now.

I'm not suer exactly what you need in order to help me, but here is the error log I'm getting.
