My phone was updated to Win phone 8.1 last week, and I was excited. However, my favorite games no longer work, and even new games that I load will only work after initial installation, and then will not load. This is very disappointing. Some of the
games that stopped working are Candy Crush Saga, and Angry Birds Star Wars. What do I need to do to make these work again? Can I go back to the older version of Windows phone?
