(SOLVED SOMEHOW) Maschine 3.11 standalone has seized up and does nothing....

I was using the above earlier today with no problem. Now all of a sudden it won't work at all.

I load the 3.1.1 standalone software. Hit play, and there is no movement, playback or sound. The onscreen play button and other controls illuminate and toggle, but nothing plays. The hardware buttons illuminate and toggle too. I can load samples, but not hear them. No audtioning works. I turn the click on, hear nothing, no movement.

Audio device selected is my Scarlett 18i8. I try to select macbook pro speakers instead, and the software just hangs and beachballs forever - Force Quit required.

Other software working fine with the Scarlett - Reaper, Live are fine.

Have tried restarting the Mac. Have tried resinstalling Maschine 3.1.1. Have tried Rosetta and non Rosetta (usually I use Rosetta).

Maschine 3.1.1 as a plugin (in Reaper or Live) DOES work.

Maschine 2, still installed, DOES work in standalone.

It's just suddenly stopped working. Not sure what's suddenly happened, I changed nothing!

Baffled.

Any suggestions?

Many thanks
