Thanks for trying to help. When I try to access the older US Open shows, it's popping up "Connection Error / We are unable to connect you to the service. Please verify that you are connect to the internet and try again".
I had contacted ESPN tech support via chat and I thought I was okay after they "refreshed" my account but after the call, I was back in the loop of either (1) re-validating my device with their activate request or (2) Connection Error as above.
What a joke this is, except I've got a subscription I can't use on my TV. When I try to watch on my PC, it's a very herky jerky video and not suited to a high speed sport like tennis.
