Mincraft doesn't come up after launching

[xXShadowTitanXx]

So when I click launch after loading minecraft and selecting the forge profile, the launcher closes but the game never comes up. I downgraded my java from 8 to 7 as was recommended, but that didn't work. After that I deleted and reinstalled forge (1.7.2 is what I'm using) (installed with with the installer), but that didn't work either. Here is my launcher log: http://pastebin.com/MsGpHVcK

 

Also, by the way, some of these verification questions are silly. "What is Lex's full nick name?:" It could be Alex, Alexis, Alexander, heck, for all we know it's Lex Luther >.>

Update to 1.7.10 AT LEAST if you want support.

1.8 would be preferable as that's the current main version.

And I am Lex, you can see my full name. It's not a silly question it's a fairly important one and it is also the one which filters out the most spam bots.

Your log tells us nothing, what launcher are you using? Also post the FML log located in the logs folder.
