Description of Problem:

I will start up the launcher. then it will connect to minecraft.net. technic will start up. when it hits the splash screen (the screen with mojang on it) it will simply shut the program down. i have tried this with hack/mine, voltz, tekkit light and classic.

This sounds like the same problem that I'm having. It only happens with Tekkit classic, technic, and hack slash mine, but the rest seem to work. I get to the mojang screen then it just closes, no error or anything it just exits.
