Multiview box upgrade ??

I tried to upgrade my X1 box so that we can get a new box to use Multiview but when I try to upgrade through the box, I get an error.  I thought I went through all of the steps a few weeks ago to get a new box but a new X1 box has not arrived yet.  I was able to order one of the smaller boxes for a different TV, but not the main X1 box.
