I am trying to make a custom modpack for the Technic Launcher, and when I open my modpack, it jumps back and forth between either opening in vanilla, or saying that it has errors opening a zip file. I am a noob to this, and I would appreciate help.
I have looked at other threads, but nothing seems to work. I am open to any suggestions.
Here is my Modpack via launcher: http://www.technicpack.net/api/modpack/killls-mumbojumbo
