My custom modpack crashes on the mojang screen

[Legomaniac359]

This is my first post on this forum, so i apologize if this is the wrong place to post this...

 

- Title: My custom modpack crashes on the mojang screen

- Type of bug: Launcher bug

- Reproduction rate: 10/10

- Steps to reproduce:

Opened the Technic Launcher

Selected my custom modpack (Narcotic Craft)

Clicked Play

Launcher disappeared

Mojang screen appears

Mojang screen disappears

Launcher reappeared

- Expected result: My modpack should fully load without crashing

- Observed result: Minecraft closes/crashes and the launcher reappears

- Logs: Launcher error report: http://pastebin.com/dGrmDc5y

             Platform URL: http://api.technicpack.net/modpack/narcotic-craft

              Download link: https://dl.dropbox.com/s/f8t96o3r4ieaf3s/modpack.zip?dl=1

- Extra Comments: I have downloaded and tested all of these mods on the client without the technic launcher and it works fine, I even have my own server for this modpack. Now, all of a sudden when i want to upload this into a modpack, then technic launcher will not run it.

I would appreciate any help that I could get!
