So I get on Minecraft and everything works perfectly fine. Launcher works, menu screen works, etc.

But, whenever I try to load a world I get this message:
(oh, and the only mod I have is single player commands)

Hi,
From looking around, Single Player Commands is only compatible with Minecraft 1.5.1 at the moment. You can try grabbing the old JAR from http://assets.minecraft.net/1_5_1/minecraft.jar and installing the mod on that.
