Hi,
For those, who like me, could not get the girl in the shop to ask the riddles.
I think I know what happened,
I think that if you open your "Web Cam" page BEFORE she tells you about the site,
You will block her from giving you the riddles.
Therefore I restarted this update and avoided the "Web Cam" site until she told me about it.
That evening I went to the site, open my page, played through all the comments.
The next day when I went back to the shop , I could now ask about the Web cam and was offered the Riddles.
