Upon typing in the parameters "-Xmx1.25G" in the Profile Options Minecraft couldn't launch (Not the problem b/c I wanted to know what would happen). I updated java 64 bit (Since the 32bit version was already updated). I launch Minecraft in the demo and I notice that the Play Demo Button says "menu.playdemo." Not really a huge bug since it still works and all, but It should be fixed. Nice music by the way Mojang!
