Help Modpack won't launch

[DoxNotch]

I'm running 1.0.10b for my server and when I try to launch the modpack it loads up, launcher closes and reopens a second later without launching the game. Any help?

Possible due to having Java 8 installed. 

Try installing Java 7 updated 73 and changing it in the launcher options.
