An issue with live TV

[Gilgamesh_48 1240]

I just, earlier today, had a problem with Live TV. It is not the usual type of live TV failure where play does not work or you can't tune to a channel or recordings don't happen or any "normal" type of failure.

What i was doing was editing the metadata for a number of channels one after another, mainly i was changing the sort field if that matters. 
As I was editing everything was working fine and I stopped to test results every 15-20 channels. On one of those interludes I suddenly got an error message: "file '/livetv' cound not be found" and  it opened in a new window that was entirely white except for the message. It looked like the screen that is produced in Chrome when you open a link in an incognito window. 

Restarting the server and restarting the Emby server's computer made no difference. 
I then deleted everything in the live TV setup and readded the tuners and guide data sources and went through the basic setup I use and everything worked perfectly.

I did not change anything else in my Emby server at all and now my live TV is again working fine but i still have the sorting to change but I will only do that in small chunks as I do NOT want to have to do it again. It is a lot of trouble for me. 

This is just a report as there is nothing else to fix but I wanted to report just in case it happens to someone else or to me again.

BTW: The spelling of "could" in the message is exactly as it was when the message happened. But i am pretty sure that cound was not what was really intended.
