My modpack won't launch.

[mainiac13]

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.

Your modpack contains both RandomThings and FastLeafDecay (FLD). Randomthing comes with its own FastLeafDecay, thus you have a conflict. Just remove FLD and you should be good to go. Well, atleast no longer have this issue.
