Hello, chasklink. Welcome to the Xfinity Forums! I would be more than happy to take a closer look at your account to see why you may receiving that error and get it cleared so you can watch HBO content again.
I see that you have already sent me a PM and I will follow up with you there. In the meantime, I would like to remind you that sending unsolicited private messages to anyone here on the forums is a direct violation of our forum guidelines. Please be sure to review those guidelines and keep them in mind for the future.
chasklink, as I have not heard back from you in some time, I have closed this thread to further comments. I hope you were able to access your HBO content again, but if you still need assistance, please feel free to start a new thread.
