I have been trying to setup my custom mod-pack onto the Technic launcher so it is easier to download. But I am having trouble, after setting everything up I launch it and it will download and unzip, after the Mojang screen it then just crash and go back to the Technic launcher.
My Pack: http://www.technicpack.net/modpack/details/ronsans-adventure-pack.407583
Edit: Due to me being an idiot I found out the problem, I had more bows installed after already finding out that the mod was broken. It works now!
