[Can't get any version of the game to load]

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?

[Old vs New]

I just recently started playing Tekkit again. I believe I previously played 1.3.2, but I could be wrong. I had a pretty specific system I used to quickly source power and materials, but a lot of the tools I used to get there appear to have been removed.

Energy Condensor

Energy Collector

Alchemy Bags

Jet Packs

Cataclysms

Equivalent Exchange system as a whole...

Have these items been replaced or were they completely removed? Also is there a good website for the new version specifically which has information and recipes for all the new items you can build?
