I'm trying to create a personal mod pack as of right now and I'm just using a few mods to start off. I think I know the two conflicting mods. They are Extra BiomesXL and ComputerCraft. I'm not sure if there is an item ID issue or what. From what I could understand, there is. I could be totally wrong though.

EDIT: I fixed it, I had to play around with item IDs in the .minecraft/config files.

Yep, it's an ID conflict. Those are simple to fix. You need to go into your config folder, and find the config file for one of those 2 mods.
Computer craft actually uses 2 different config files.
CCTurtle.cfg
and
ComputerCraft.cfg

Extrabiomes actually puts it's config in a folder in the config folder
config\extrabiomes\extrabiomes.cfg

But you need to open one of the configs, with notepad or any other text editor, and change the ID that is conflicting to a new number.

So from your error you can see this.

java.lang.IllegalArgumentException: Slot 207 is already occupied by [email protected] when adding [email protected]

You need to find the 207 value and change it to something else. I normally start by adding a 1 in front, so make it 1207.
You can use anything up to 4096.

It's likely you will get other conflicts after fixing this one. (If I remember right all the CC ones conflict with extra biomes. Even the ones in CCturtle

Some people like to go into all their config files at the start and reassign everything.
All ExtraBiomes IDs get assigned into 200-300 range.
Industrial craft gets 300-400
Computer Craft gets 400-500
etc.
etc. etc.

That method is a bit overkill, imho, I'd rather just deal with the conflicts when they occur.
