There is trouble logging into Netflix via Media Center.The users are getting “Account Error – There is a problem with your account. Please sign in again.”
There is a very long discussion Media Center Nexflix Account Error Problems
I saw twitter posts also.
When users are trying to log in through the Windows Media Center integration they are receiving the above error.
Deleting the HKCU\Software\Microsoft\Windows\CurrentVersion\Media Center\Extensions\Netflix key doesn’t help either.
Unfortunately till now there is no workaround.
