Weird Popup

I only speak English, and I keep getting a popup when I open the game. There is one line of text with two buttons underneath. I press the silver one, and it closes the game. I press the gold one, and it takes me to the app's store page. I usually use a US iTunes account but have a Chinese one for this app. I checked to see if there is an update for the app but found nothing. It started about a month ago. I'm still new to the game. How do I get rid of the popup or play the game? Also, is there anywhere that has a good translation of the UI and/or guides for English users? Sorry for the inconvenience.
