I downloaded Shift 2 days ago and played 16 hours of it. Later today, when I tried to play again, the game's "Play" option wasn't there. Instead, there was a download option. It started the download at 88%, I assumed it was updating files. At 97%, the update failed, and I had to cancel download,which wiped all the files. I attempted a re-download, but at 93%, the same error popped up. Any solutions?
