I'm not sure what the issue is because it seems a little contractive, I pressed the newest game Marching Zombies and get the vb error in the title of this thread, however I can play the other newest games. A search for the game does not show anything and even a search for just the word zombie does not garner results. so I don't know if that game may be a category that I can't see or if it is a lingering cache of a game removed .
I am able to play and download Angry Birds listed in the same widget.
