I'm actually super excited to try out the Horizons modpack; it looks really awesome. But it won't launch for me; I've installed the modpack, but when I try to launch it, the "Launch" button goes grey, and then nothing happens. Have left my comp for 15+ minutes, and it doesn't even bring up Minecraft; just sits uselessly at the launcher and hangs; can't do anything but quit. Fwiw; I can play FTB Unleashed just fine. Here's a pastebin of my FTB console - http://pastebin.com/PDffCfcX I've tried updating to Java 7, but that leaves me unable to run Minecraft in any capacity, much less Horizons. Not sure what's going on, or if there's even a fix at this point, but hopefully this is helpful for y'all to figure out what's up & fix it in the future!
