I live in Germany and I am using Windows 8.
I was able to finish all challenges on Feb. 1, 2, 5, 10, 11, 12, 13, 14,17. 19 and 20. On the other days I could only play one or two games. When I click on those games it starts loading........ and never ends up. Usually I succeed in every game and I would like to go on. It is disgusting and it nerves.. What can I do?
