Games : Minecraft forge 1.7.10 quit working

Been building a modpack using technic, a personal thing. It started out working and running well when i played it with lucky blocks(the rainbow block edition) and orespawn. but after adding in a few mods, it will no longer play, or even launch. The modpack selection screen disappears, and a few seconds later reapears when it fails to load the launcher.

I have uninstalled and reinstalled all the mods, even trying to take it back to just the original two i started with, it will not launch at all.
