Regarding this... It turned out my firewall started auto-sandboxing the game after the update, which interfered with the keyboard controls.
How stupid do I feel now?
Well that is odd because I had the exact same keyboard commands issue after the installing and then trying to play, but tI went away once I had restarted the game (not the computer). Maybe your restart of the game did not work because the game was in the "sandbox," while mine was not.
