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?

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?
