DTS Track Playback Error

Hello,

In my Infuse player which I have upgraded to the Pro version in my Apple TV, when I playback a mkv file which has a DTS track encoded in it, it gives me a message to “Unlock for free”.

When I hit that button I get an error message that reads “unknown product identifier”. I have tried to uninstall & reinstall and same story.

Any thoughts on what can be done?

Thanks!
