Um... Can you fix the error on your mod pack yet?

What's the error? If you're referring to the forestry problem it's getting worked out. Be specific as I don't know what "the error" you're mentioning is.

You should download/view the log yourself, It's at: http://www.mediafire.com/view/9j8ben71irix27q/ForgeModLoader-client-0.log
Looks like you need to increase your PermGen size (done in the cog in the top right corner of the launcher) also update the pack.
