your refresh instructions for error code 722 don't work - DirecTV

I have used Direct TV from my RV when on the road many times from this location.
Now I get error code 722, which is not fixed by re-booting.
I can't call you because I am off the grid. Please help!

I will request a refund for this month when I am home again.
