LMS on ReadyNAS NVX questions

I've been running LMS on my ReadyNAS for years, back in February I updated to 7.9 and its still working great.

I've updated the BBCXMLParser.pm for the BBC iPlayer plugin and most streams seem to be working fine. I want to delete the cache, plus to move around many music folders. So I figured I'd shutdown the LMS.

1. Disabling the LMS from the ReadyNAS admin web UI isn't stopping the LMS, and after a reboot, although the LMS starts, the UI reports failed. https://192.168.1.11/admin/

2. Is there a way from within the LMS web UI to stop the LMS? I've looked everywhere but can't see it for looking.

I understand stopping the LMS from inside it's own UI is terminal, but assuming it starts again if I reboot the ReadyNAS...

any ideas on 1. or 2. ?
