Game Crash

I cannot play the game. Every time I press play in the start up menu I get this error message.

Completely ignored arguments: [--nativeLauncherVersion, 1206]
[07:01:55] [Client thread/INFO]: Setting user: T4stemyRainbow
[07:01:56] [Client thread/INFO]: LWJGL Version: 2.9.4

What can I do to fix this?

Thank you,
Kevin Cowern
