I have a subscription to HBO and I'm trying to watch it on my laptop.
For some reason I can not sign into HBO GO,even after resetting my password and going to Xfinity's TV Go app on my phone I can't sign in.
Hmmm, have you been able to login to HBO Go before this? If you have and are having issues, what are the symptoms / error message that is being displayed when you try to login? If you are accessing the service via Web browser, try using a different browser or clearing the cache on your current one. If you don't have Google Chrome or Mozilla Firefox installed, I'd start there.
