wrote: The older version only worked in IE because it used Microsoft Silverlight, support for which was dropped by all the other browsers. Hence Sky developed the replacement app.
The device ID was generated by a Silverlight specific function, so couldn't be shared with this replacement app, meaning there's a one-off re-registration needed.
Another poster reported that they cleared the PFE-9500 error by connecting an audio output device - https://helpforum.sky.com/t5/Sky-Go-Apps/sky-gp/m-p/2821795 . Although i've asked Sky for further details on that error code.
Sky need to do more development then because the new app simply doesn't work!
