Windows .exe FTB Unleashed not launching

[Darknight1243]

I cannot launch the Unleashed modpack from my launcher. When I attempt to launch the Unleashed modpack my launcher attempts to start Minecraft but it won't load the Minecraft Class (Pastebin linked). the Minecraft window will never open no matter how long i leave it sitting, however, the program does not actually freeze as I can choose other options on whatever tab I'm looking at as most buttons and tabs are greyed out and become unclickable like the program does before closing and opening Minecraft. I have updated Java to the current version of Java 7, I have deleted and reinstalled the Unleashed files, and I have used different versions of the pack but none of these things have solved my problem. All other modpacks load fine.
