Can't get any version of the game to load

[MGTurbo2]

So i just reformatted my PC and now I cannot get anything to work.  I downloaded the latest launcher and a few mod packs.  When I hit play the launcher goes away for a few seconds or less and pops back up and the game never loads.  When i try tekkit classic i just get a new window with a white screen that never goes away.  When I close that the launcher comes back.  What do I do?
