Infinite download. (Fortnite)

A long time ago and decided to set this wonderful game. Then deleted. I recently decided to download again, but there was a problem that when the game starts I have a progress bar almost reaches the end and nothing else happens. Went into task Manager, it says that the fortnight is not responding. the Icon below, but it is fully transparent and to expand the game impossible. If someone knows how to solve it, help please.
