The link looks right have you done a hard reset since your update?
Unplug the power cord and shut the unit off and Press and Hold the power button and the "Down" volume button together until after the normal start up screen appears and is joined by some small print at the top of the screen then let them both go. After a few seconds you should see a couple of shapes in the middle of the screen called "Wipe Data" and "Android". Wait a few more seconds until the term "Cold Boot" appears in the list near the top of the screens and just press and release the "Down" volume button again and let it reboot. If you own the dock be sure and do this with the dock connected.
