Minimserver on Qnap NAS has died - help please.

[Budgie]

My media is stored on an Qnap NAS (TS 559 Pro II) and served by minimiserver. It has worked almost without interruption other than updates for many years.
Last night on trying to play a track I found nothing. On inspection it is clear that minimserver is not running.
I considered re-installing but I cannot access the installation instructions, hence this message.
BTW I have no idea which download I should use. The processor is an Intel Atom so which OS should I download?
Hope you can help.

I have found that previous updates had not been correctly installed. I have just downloaded the latest qpkg file and installed and all is now OK.
