Launcher won't stay up

[Zirawulf]

Ive been trying to load up the 1.7.10 mod pack many times today It goes through its normal steps to load up but once done, it sits on the spash screen for a few seconds then crashes...

Here is my crash log from when I had 3gb of ram allocated to the launcher (I think)

I then tried to have 4gb of ram for it and it crashed again

I installed and loaded up Vanilla and it worked fine. So I'm not sure what the problem is..

Not even going to bother helping as long as you have Xray in your pack. Go cheat somewhere else.

Edit: Well, good for you that I didn't see it in your second report:
