For some reason none of my modpacks will open. They act like they will, the launcher disappears but comes right back. I've set the ram allocation to the full 7 gigs, tried uninstalling and reinstalling minecraft and technic, and I've tried rolling java back to 7 and then returning to 8, nothing seems to work. Any ideas would be useful. Log to follow : http://pastebin.com/pVnutK6R thank you
