Modpack crashes as soon as it starts up

[Dbrzez]

When I open my custom modpack that I have loaded up to technic, it closes immediately and returns me to the technic launcher. My modpack is set up correctly with a bin folder containing forge.jar and the mods folder containing all of my mods. Here are the logs:

don't paste the log content directly on your post, use a pastebin service instead. Certain logs can be ridiculously long and it makes reading your post hard when you need to scroll down for several minutes before anyone can get to reply button.

post your dropbox link to the pack, so we can see how you set it up

Edit. also, this belongs in Platform Pagoda for custom pack discussions, Moved
