Minecraft Forums

I'm trying to use both Modloader and Forge in Magic Launcher (which is the only way I know how to use mods) in order to use DrZharks MoCreatures Mod v4.3.1. I'm running into issues. I've heard that Modloader needs to be at the top of the Setup list, but then Forge has 4 errors. When Forge is at the top, it only has one error, but now Modloader is "not compatible." So I tried just Forge, but it still has 1 error. This is the error message that came up when I tested it with only Forge and the mod:


*** MagicMinecraftLauncher 1.0.0 ***

Can anybody tell me what I'm doing wrong or what I need to do to get this mod to work?

Ok, I tried installing the mod the old-fashioned way, and this is the error message I get. Remember, I want to use the Mo' Creatures mod from DrZhark.
