Nevermind. Please delete this post.

If you're asking about the screen on the left, you can't download your games from there. It's your profile page and it has been designed that way. If you hover your mouse cursor over your nickname in the navigation bar (instead of clicking it), you'll see a drop down menu, and from that menu select "Games".

Edit: I was too late, and I'm pretty sure that when I hit reply button, there was no edit visible yet ;)
