Cant update

I love playing the game, but since the newest update my phone will not download the update for some reason. I will click the update button then it just sits there and doesnt update doesnt do anything. I left it there for a whole day and went back to see if it had updated or even began or made progress on downloading and nothing! If I delete the app and reload it will that cause me to lose all my heroes and purchases and everything else?
