[MCL-724] 1.6 Launcher Bug

I downloaded the 1.0.6 launcher from mojang.com, and everytime I enter my username and password it has 2 options. Log out and play, but for some reason when I click play nothing happens. I waited for about 30 minutes and still nothing. So I pressed return on my keyboard and it took me to the development console and said playing offline as LTCR. My internet connection is fine and I'm not dis-connected from the internet. But it still NEVER let's me play 1.6.

Couldn't go online
