Recyclin

I do play Hexxit, a lot actually, but I just get into the mood to play something technical but not have to do much in gathering resources, more based around large structures that I build myself for processing and creating power facilities and what not, sometimes the RPG element in Hexxit gets boring.

Is there anyway that any of the older mods can be added back in, I miss IC2 and Railcraft, they made the experience of the modpack last longer. You know? It made you have more to work towards. If not can I have some help with adding them in manually, its crashing whenever I try.

Hey forum, I'm looking for some help with this crash I keep having when I launch Big Dig and Tekkit. Heres the report http://pastebin.com/Bp6vMhST if anyone can help me fix this I would very much apreciate it.
