I am having the same problem, which did not exist until I installed this new version. As for the verification questions, it took me ages to work out what on earth they meant when asking 'which of these does not have a pair?' A pair of what?
p.s. After reaching a stalemate I decided to click on the Settings icon. I copied the path shown to where the data was stored on my computer and could see a file in 'Content174', which I think was just the system update. But then, after closing the settings I was presented with the update screen again, so I repeated the request and it is now downloading. I have been noticing for years now, that TomTom doesn't seem to have any group of people to check the work of the programmers before releasing it, relying entirely on customers to do all the bug reporting for them.
