Subtitle set up

Hi Guys,

New to the media box stuff, so need some help.

I'd like to set up subtitles and have entered the system settings in XBMC and set default language and default provider, even downloading the specific provider.

I started a movie and attempted to download subtitles but I receive the message 'no subtitle service installed.'

What have I missed?

Also, I assume most settings are changed via the XBMC app?
