Direwolf20 not launching

[Terny]

I've been using FTB Unleashed for quite some time with no issues wanted to try out Direwolf20 (v1.0.14). It downloaded itself but never ran. Every time I try launching it it goes back to main menu.

Here's the pastbin:

Any help will be much appreciated.

Not sure if this is the source of your problem, but

[01:36:08] [INFO] LaunchFrame.main:194: System memory: 4018M free, 8072M total

vs

[01:36:22] [INFO] MinecraftLauncherNew.setMemory:158: Setting MaxMemory to 5376

You're potentially trying to assign more memory to Java than you have free. Try toning down your max RAM to 3 GB; that's more than enough unless you're using a x128 texture pack or higher.

I slid it down to 2.50 GB and problem persists.

If you have a world to back up for the Direwolf20 pack, back it up. Then under Options, click "Force Update" then try running the pack again. Hopefully that will get things going for you.

Force Updated and it's still not working. Reinstalled (deleted&downloaded) FTB and still nothing. Also resintalled Java.

Edit: Tried it with Monster pack but same error. Only Unleashed seems to work.
