Instant Crash

What I expected to happen was I would log in, and play on a server.

What actually happened was I logged in, and I was looking at the sky and then a few seconds later, I crashed for the first time today.

1. Log into Minecraft 1.7.9
2. Click on multiplayer
3.Click on direct connect
4.Type the Server IP: us.mineplex.com
5.Wait for it to crash
