I couldn't even log in, when I tried to, the launcher said Minecraft had crashed.

Put the summary of the bug you're having here

What I expected to happen was...:
To get logged in, without a problem. Maybe a little lag.

What actually happened was...:
It didn't log me it, and said the game had crashed, before I had even gotten out of the launcher.

Steps to Reproduce:
1. Download the new Launcher, open it.
2. Log in with your account, and hit play.
3. The Game will crash in the launcher state. I didn't even see the game once.
