For some odd reason I can't play on minecraft

Ever since 1.6.1 has came out there is no "Play in your browser" button or "Play in demo" button after I log into Minecraft I will take some screen shots on what I am talking about. These screen shot will SHOW you step by step what I have tried and nothing has worked. I don't understand why it is doing this, this did not start until July 2,2013. I hope this time you will understand what I am talking about. Yes I have cleaned out my computer, and ran Java updates.
Thanks,
