Token error. On the Login screen in the MyM launcher remove and readd your account. That should fix it. Also make sure you are using the latest version 4.4.0.3
Running latest version of launcher, removed and readded account. Still closing just seconds after starting
It looks like you may have installed the Java development Kit instead of the Runtime. Some versions of Minecraft dont like Java 8 past v 291. So reinstall java and set the Launcher to use that install and you should be ok.
