Changed DVR Recording Directory but now Enable DVR is stuck spinning

On my QNAP, I changed the DVR recording directory in settings but now Enable DVR is stuck spinning. How can I get the DVR to run again with the new directory?

Can you restart the dvr via QNAP apps interface

I'm sorry - how can I do that? I can't find where I can do that.

On your QNAP web UI where you installed the dvr

When I left-click on the Channels app, it opens the setup page. When I right-click, I get the attached screen shot that only allows to 2 options:

Channels%20DVR%20app%20menu

Is there another place I'm missing?

That's the home screen right? There should be an apps interface where all the installed apps are listed and you can start/stop/etc.

Yes, it was the home screen.

Found the apps folder location. Was able to stop and start it. Looks to be working again. Thanks!
