What should I do about it?

What? I haven't moved any of my mods into minecraft.jar! I use Magiclauncher 0.9.9, so I dont need to load anything into minecraft.jar. Right? btw I use windows

I just downloaded forge so I could use the Mo' Animals Mod. I use MagicLauncher to manage my mods, and it told me a forge was required, so I downloaded MCforge and added it to my list of active mods. Now, whenever I have it enabled, my game crashes upon startup. Could Someone please help me with this?
