App wont complete download/open

Downloaded the update and now the app wont open. Its just stuck in the middle of installing. Extra frustrating since this means Im missing out on the event AND on keeping up my progress to win the timed completions. Cant believe game loft would release and update to fix minor bugs that makes the entire game stop working. Seriously? That makes no sense
