Quoted from msj2222:
Been trying to update but my screen has stayed blank for about 20 mins...any suggestions?
Update: After a over an hour, screen was still black so I shut the game down, removed the usb stick, and restarted. Seems like the update installed as it says V1.56. Did others experience this? Did it not install correctly and should I retry?
If it says V1.56, then you're good to go.
