Can't access Properties tabs for MinimServer

[nickc]

With my desktop pc still out of action, I've brought my old mid-'90s machine back into action, running Ubuntu 10.04, and installed MinimWatch on it. No problem, and it's found MinimServer running on the QNAP TS-109. Having managed to reinstall MinimServer on the QNAP (see an earlier post - thank you, Simon!) following a problematic shutdown, I now want to reinstall MinimStreamer so I can listen to internet radio. But I can't access the Properties of MinimServer, which I need to do of course to install the MinimStreamer package. The other items in the MinimWatch menu all work, and the MinimWatch log has several repeated lines as follows:

Error 1 [Unknown] invoking GetProperty on remote runtime monitor

The MinimServer log doesn't appear to contain anything relevant, merely listing various tagging errors and stating that MinimStreamer is needed to play the internet radio playlists.

Any suggestions as to what I should do to garner further information in order to diagnose the problem and put it right? And is there any other way of installing MinimStreamer on the QNAP?
