Hey, my Minecraft was working fine just yesterday no problems in both single player or multi, in both 1.8.8 and the latest snapshot (15w37a)..
Then today I started the launcher (Minecraft.exe not the installed version) and clicked play for Minecraft version 1.8.8 and it just sat there saying "Launching". I waited a whole half hour before closing it and relaunching to the same thing. I then tried the Snapshot same result, then version 1.7.2 at random same result. So I reinstalled Minecraft and updated Java to make sure that was not the problem. Now instead of simply just hanging there saying "Launching" it shows a new Tab "Game Output (My Username)" and this message in the box below.
