Friend of mine didn't pay his bill so they cut off his service. Paid the bill and the late fee and now one of his receivers aren't working. It gets the #731 error and I looked it up and it saids that 731 means the access card is full and needs to be called in. That's a problem since the PPV is filled. I'm wondering why this is only happening to one receiver when all the other receiver's PPV are full as well but work.
