That helps! If you download and launch the game, and go into Amir's chapters, can you see that a greyed-out Finale chapter at the bottom? 
If so, then the game should have all the new content and let you unlock chapter seven (if you played through the previous chapter). I'm not sure why that update time stamp is incorrect as it is showing the correct version number AND all that information is showing up correct for me in multiple browsers. In the meantime, I'll send in a help ticket lol.

Can confirm it is indeed the correct version. It wasn't before when I downloaded it right after the update came out, then when I came back tonight and downloaded it again it was right.
