teddywon,

Have you been able to access the Netflix widget before the latest update, or was there a point in time where the widget was working and then stopped working?

You might try to re-activate the account (deactivate on the website, then reactivate through the TV) to see if it's there's something with the connection from the membership side. Other than that, you might check with Netflix to see if there's troubleshooting available for your account. They can be reached at 866-716-0414.
