I have been using HBO GO for the last month and haven't had any problems. Just last night, when trying to log in, I got an error message. Today, when trying to log in, it took me to the pick my provider page to select. I choose Directv and it took me to a weblink. I clicked it and nothing happended. So, I sent the developer an e-mail, uninstalled and went to reinstall. Its no longer in the market. I even tried on Wifi in airplane mode, in case AT&T was blocking it. I have an Atrix.
