I decided to check out whats new in Minecraft. I havent played in a few years. And saw a video this morning on some new updates. So I reinstalled it. (Latest version.) Updated JAVA to latest and the game will not start. Launcher starts but when I click play I get a game crash. Cant find where it is keeping the logs so I uploaded a screenshot of the log and crash. Using windows 8.1.

So how do I change my IGN? I cant seem to find a way to do that.
It's not about your in-game name, it's about your windows user name (Necrosapien!) that contains an exclamation mark.
If you don't know how to change your windows user name, please use the Community Support IRC chat, there are people in there who can help you.
Your windows user name contains an exclamation mark, which makes it impossible to run Minecraft. See MCL-774
