There has been a number of issues this week with some customers missing channels, or getting the 721 Error, Channel Not Purchased, when it was indeed a channel they should receive. If you are ever missing channels, please use this link to reauthorize your receivers prior to calling for help: https://www.directv.com/DTVAPP/mydirectv/mysystem/mySystemResendAuthorization.jsp You will need to login to DirecTV.com with your email and password. You can also call 800-531-5000 and tell the automated system Error 721. Both methods do the same thing. If it still fails, you'll need to call tech support (or actually purchase the channel you're trying to get, if you haven't already).
