Hexxit is Continually Crashing Before the Mojang Screen Disappears

[ProfessionalPest]

When I open the Lancher, all is well, until I select play on Hexxit. I would expect the Mojang logo to do its thing for a while, then the screen with singleplayer/multiplayer options to appear so I can play. What ends up happening is the Mojang screen appears, then 10-20 seconds later, Minecraft crashes. This has happened 10/10 times. I have changed my allotted RAM from 1.5 to 2, and then to 2.5, but neither has worked. This is the most recent crash report to appear: C:\Users\Boys\AppData\Roaming\.technic\modpacks\hexxit\crash-reports\crash-2015-08-31_22.06.36-client.txt
