modpack Modpack won't start

[WindPugsX]

So basically, after a new update came to PixelSpark the modpack hasn't been able to load on my technic launcher. It has 3gb of RAM allocated and its on Java System 64-bit.

Basically what will happen is, I click "Play" on the launcher and then it will start up minecraft. Then after a while it will go to a black screen and close. Then the technic launcher will open up again.

This is really frustrating considering I don't understand computers and coding. Any help would be greatly appreciated.
