I click lunch.
It's download and then close reset on main launcher screen. Nothing open.
Does someone have the same problem?
How to fix?

[INFO] LaunchFrame.main:189: Java version: 1.6.0_45

Welcome. You have a really old version of Java installed. Uninstall Java 6 and any other version of Java that is installed. Restart your computer then install Java 7u45 64bit. Then restart again. If that does not fix the problem please post a new console log to pastebin.
