Hi, Minecrafters.
I'm just chilling and playing Minecraft, when suddenly, I was going to open a singleplayer world.
And then it goes Building terrain for a while, and it crashed.

I had no problem before i installed the 2 mods, Harder Peaceful (Wuppy's mod) and Biomes O' Plenty.

So I think the problem comes from one of these two mods, or maybe they are conflicting.

Here's the Crash Log:

One of your mods requires forge, and you don't have forge installed.

You can't use forge and modloader together. Tho, forge will work for most modloader mods. It doesn't work the other way around. Modloader is missing most of the forge features, while forge incorporates most of the same features as modloader, plus tons more.

Man, Kudos to you! I can finally play minecraft again! :DDDDDDD

Thanks very much, May Notch bless your merit
