Black Screen After Mojang

[northstarhero]

I've been surfing the net for the past couple of hours trying to find a solution to this and I've about lost my mind in the process @_@

Every time I fire up Feed The Beast Unleashed it gets all the way to the Mojang screen... sits there for a bit... and then the screen goes blank and just sits there.

I've got the log here: http://pastebin.com/3zGUPka0

If anybody can help me I would greatly appreciate it!!!

This error is often caused by an over zealous antivirus program. Add the folder, C:\Users\Amber\Documents\Games, to the exclusions list of your antivirus program. Be sure to check any boxes that say 'include sub-folders' when you do so it adds the files inside the other folders below. Also you might want to get the 64bit version of Java, and remove all other versions and 32bit versions, so you can allocate more than 1GB in the launcher.
