Attack of the B-Team Won't Launch

[TheAlbatros]

Hello, I downloaded 'Attack of the B-Team Modpack' but when I click to play it loads something and then launcher disappears but modpack is not opening and then launcher comes up again like nothing happened...(It's not giving me any messages like 'crash' and my java version is:Java 7 Update 51)
By the way I've reset modpack but nothing changed and I've  got some 'warning's on my console but I don't understand what should I do.
Console :

That's why you should make a Bug Report

hi i changed the amount of ram tekkit uses and now it wont lead attack of the b team it just says not responding 

[Thefootballgamer]

try going to %appdata% locate roaming go to technic folder locate the modpack folder then find attack-of-the-b-team folder and delete the whole folder then reinstall bteam from the launcher

This fixed mine

Also try allocating more RAM to the technic launcher.

if you experience issues then make a report on the Tracker. Don't post on Modpack Discussion if the modpack or the launcher wont work or the RAM is too low.
