Technic Launcher Problems

[Ace Dusk]

I am having a major problem with the technic launcher. I can't play any of the games because when I press play, it loads and white screens for a second and then brings me back to the same screen. My friend helped bring this code from the technic launcher which is the link below. I have been trying different methods for 3 days and can't figure out a solution. No games work like tekkit Classic, vanilla, etc. I tried different versions of Java, I think the code below ran on was Java 7 update 79 (64-bit). I have allocated 2 gb of Java memory to this. I am running Windows 8. Thanks for the help in advance!
