So i've made my own modpack, uploaded it and stuff, and can't seem to get it to work. I once got its' predecessor to work in the past, but i don't know whats wrong with this one. I press play, the launcher disappears as though it will launch the game, but then the launcher just comes back up and nothing happens.
Here is the console log

EDIT: The name of my mod is Project HC 2.0, and the predecessor is Project HC. I cannot confirm that the original works at this point, nor do i care. I just want 2.0 to work, and need to know what the problem is.
