I got on over an hour ago, and the estimated time is over 5 more hours. I use steam, but does it REALLY need to take that long?
I’m not sure if i can leave my PC on overnight to let it update, and I’m certainly not going to be awake all night. What do I do? 
I was wondering where you were. My update only took somewhere around 10-15 minutes! Maybe it’s an issue with Steam, or maybe there was other heavy internet activity in your household?
its because they just rid of dial up . hope that helps/
Did you try changing the download region or clearing the download cach in steam?
