Sounds like the update didn't work. It took mine 15-20 minutes to download, then I got a dialog saying something like "This is a two part update. The system will restart then the update will continue." Sorry I didn't copy down the exact words, but this dialog was in perfect English in contrast to the earlier dialogs.
To check, you could go to "Settings", then "About Tablet" (last choice, need to scroll down to see it), then "System Updates". It then checks for updates, and if you've been updated, it says "Your system is currently up to date". If not, hopefully it will give you the option to retry the update.
