I had previously paid to unlock emby, now it won't playback media and says I need to unlock again.  I use nvidia shield, it says its version "1.8.24g expired" on the shield screen.  My windows server says version 4.4.3.0.   I tried restarting server on windows, I uninstalled and reinstalled the app on shield. Playback works on my android phone.   If I scroll down in the nvidia shield app, the unlock icon is unlocked, but when you click on it, it has emby premiere, unlock, restore
