All Modpacks Not Working :(

[BLuE_GaMeR]

Hello Feed The Beast. My friend have a bug on ftb launcher. When open any modpack is closed in mojang screen.

EDIT: I found a log

My fried operating system:

OS: Windows 7 Ultimate SP1 32-bit
Java Version: 7 Update 45
RAM: 2 GB

Know a solution?

I have some bad news for you. Please read here about the limitations of trying to run most of the new 1.6.4 FTB packs on a 32bit system.
