Download queue

A few weeks ago I saw that Forza 6 was in my queue and was at almost 5,000% complete. I was able to get in to the game menu, but was unable to race. I looked around the menu and saw that some cars and tracks needed to be installed, had small arrows next to them. I tried to load them manually, but was discouraged as this would take hours, so I gave up and uninstalled the game. I reinstalled the game and everything seemed to be fine. I was able to recover all the DLCs that I had and my current progress. I got on my XBOX One today and found that Forza 6 was again in my queue and is currently up to 1,527%. I don’t want to uninstall/reinstall weekly just to play the game. As I mentioned, I am on the XBOX ONE and an external hard drive, a 3TB My Book.

Try doing a system reset (hard boot) as below:
1 – from the Dashboard, out of all games, hold the X button on the front of the console down until it shuts the system down.
2 – Disconnect the external power from the wall plug (or at least disconnect the wall-side connector on the power pack itself.
3 – WAIT until all power drains from the external power pack (no light, either white or dull orange showing on the pack).
4 – Reconnect the power supply to the electrical outlet.
5 – Restart the console in the usual manner, i.e., either with the controller or a short push on the X button on the front of the X1.
6 – WAIT until the console self-checks and fully boots to the Dashboard before attempting anything.

If you don’t disconnect the external power pack and let the power completely drain out, the system is still retaining “old” stuff and not resetting.

Thanks Snowowl for the help. I tried your reset method a couple of times with different time delays (waited for the light to go out and waited your over an hour), but it didn’t seem to work. I am going to uninstall and reinstall on the internal hard drive and see if that works.

I would contact Xbox Support - Xbox Support - because the "over 100% reading was an issue months ago during the recent beta builds, and supposedly was corrected properly. I haven’t seen it in probably four or five months on any update, either Xbox One system or a game content update. Support may recommend something to fix it.
