Emby Theater reporting no Premiere Subscription

[GrotShot 28]

I changed server PCs today and did a Server Backup using the plugin, restored on the new PC and let a library scan complete. I then checked that all libraries were accessible and that a movie played from the web interface. Next I tried Emby Theater and it reports no active Premiere Subscription even though the key has been successfully copied over during the backup & restore process. Server Log attached from an attempted play of the movie in Emby Theater.

Ok, so nobody gives a monkey that this doesn't work??

Hi, sorry, I think we missed this. Can you please try removing your key from the server, then re-entering it? Thanks !

OK - I removed key, saved, restarted Server, added key, saved, restarted Server and all is well now.

Thanks for your help.
