metronome bug

Suddenly I’m having problems with metronome in Artist 9.5, it worked fine until now. Using Midi just a monotonous piano key sound which is out of step with the music. When I try to use Audio click, either with Steinberg sounds or with custom audio there is nothing to be heard.
I’ve wasted about a day on this and I’m not such a dummy, having had Cubase since first midi version in 1990…
When I look for help a lot of the items refer to Cubase 9.5 (eg mentioning control room which I don’t have in Artist) and I’m certainly not going to spend money to upgrade just to get the metronome working.
I can’t understand why the Cubase software has become so clunky, Nuendo 4.3 was such a simple, reliable and clear programme to use ten years ago but we seem to have gon backwards in some ways.
