Yeah it just started working again Not sure why really, I didn't change any settings whatsoever within the launcher and then it started up

True dat Just run the launcher again and it should work, that's what I did.

SOLVED. I guess, I really have no clue why it's working now after I failed 20 times in a row, but I'm not complaining, I can play any modpack I want now :D

This affects Lion and Mountain Lion? Oh God. Okay, if anyone could tell us what the issue is, why this happens and how to fix it that'd be brilliant. If not a fix for it is all we need :)

Launcher Version: 1.0.1.3 Operating System: Mac OS X 10.7 Java Version: Java 1.7.0_05-b06 Antivirus Program: iAntiVirus Description of Problem: I start up the launcher, put my login details in and select a modpack. Everything for that modpack downloads, no issues there, which is good. When everything's downloaded it tries to run the modpack, but it crashes before I get to the Mojang screen...and when I say crashes I mean it starts the window for Tekkit or whatever, but then just stops completely without giving me any error messages or anything. Any help would be very good because I want to play with my friends on Tekkit. Error Messages: None Appear Error Log: [11:23:48] [sEVERE] Launcher is starting....
