Crash on world load

[Wiseshortman]

I'm new to Feed the Beast, so I have no idea what is happening.
Every time I try to create a world, the game freezes as it's loading. After that, the only thing I can do it force it to close.
I'm using direwolf20's pack, as well as optifine and mocreatures(plus the mods required for it)

I've tried loading it without the additional ones, and it works fine. But, I would like to play with them.
I'm trying to use the seed -799363941642247584

Here is the pastebin: http://pastebin.com/AK4kjz0P

once it hits the last part, it says it's shutting down internal server.

I hope someone can help out.

OptiFine D5 im guessing. Delete it and install C5 instead.

I took a look for optifine C5, but there was none on the page that I could see.
I tried using C3 and the same thnig happened, but, at the end of it, these lines appeared before it started to shut down the internal servers again:
2013-03-27 11:08:05 [INFO] [STDERR] Unable to load class: codechicken.nei.plugins.redpower.NEIRedPowerConfig

You should be using java 7.
Also take the spaces out of your Launchers file path
And you want to be using Optifine D4 or D5 with this build

You are awesome! Updating Java fixed it. Thanks!
