Even though I activated my ROKU through the PBS website on the computer (submitting the code which appeared on the TV screen) and was told that ROKU was activated, the PBS channel on ROKU keeps telling me I need to become a passbook member whenever I try to play a passbook video. I already am a passbook member. All non-passbook videos play just fine. I tried (about 4 times) the sequence for deactivation and reactivation of the ROKU device but still no luck. Can anyone help? This seems to be an endless loop. Thank you!
