What in holy fudge. You have way too much stuff in your pack archive, and there are things in the /bin/ folder I've never seen before.

• The /bin/ folder should contain one file: modpack.jar . This file is simply the Forge universal binary JAR file renamed to modpack.jar.
• Your modpack archive should not contain a /asm/ folder.

Removing the extraneous files listed above, and fixing the modpack.jar file allowed me to start your pack.
