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?

 

Error report:

 

*** MagicMinecraftLauncher 0.9.9 ***

java.lang.VerifyError: (class: net/minecraft/client/Minecraft, method: usePortal signature: (ILox;)V) Incompatible argument to function

Does not sound like you are adding forge to the jar perhaps?

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

Doesnt matter if you mover it in or MagicLauncher does

its the same thing.

Something you're using screws with Minecraft.class in a way that should not be, and crashes, doesnt seem to be a forge issue.

What should I do about it?

 

Dont use a mod, that edits base classes...

Talk to the mod dev and tell them to stop being stupid and quit editing base classes.
