Being an IT person does not mean I understand editing the inner workings of programs, apparently.

I've been trying to mod Vanilla. The two mods I intend to add are DrZhark's Mo'Creatures and Jammy's Furniture Mod. However, despite having read many FAQs and guides, there are a few things I don't get and a few immediate problems I can see.

1. Jammy's Furniture Mod came in it's own separate "mods" folder upon being added into .minecraft/mods. I deleted this; was that a good idea?

2. DrZhark mentions needing to install GUI Api into the "/coremods" folder (under "How to install the Mo'Creatures mod"). I do not have this folder; where should I add it?
EDIT: found this, it was hiding.

3. As for the "META INF" folder in the Minecraft .jar, do you delete just the original, or the original AND the Forge META INF folder as well?

I enlisted the help of a much younger player, D (my brother), who attempted to install the mod after I had failed. We wiped MC, FML and Jammy's Furniture Mod from the computer, reinstalled the files and tried again, and it continued to crash. D has been helpful in solving 90% of my problems, but even he has no idea why it is crashing. I'm including both crash logs, from before and after deleting the file outlined in question one.

Is there any way to fix this, or are the two mods just incompatible? Or am I missing something extremely obvious and simple? Any help is appreciated. I

I've waited four days, does anyone know? I'm getting rather desperate.

You delete the the first META-INF and keep the new one brought in by Forge. As for 1, is it forge compatable? Does it need forge?

GENERATION 27: The first time you see this, copy it into your sig on any forum and add 1 to the generation. Social experiment.

Okay, I did do the thing with the META-INF correctly in that case. I am not sure about Forge compatibility on the first one, I tried Modloader on that one if I remember correctly. I didn't get Forge until I tried Mo'Creatures... I think...

FML is in forge :Diamond:

(FML Means Forge Mod Loader)
Modloader Is INCOMPATIBLE with forge so they made FML
So you don't need to worry about modloader mods being incompatible with forge:)
