Maybe you have not yet re-installed the drivers for the sound cards? The evidence of the failure is the latency figure of zero. The only attachment was a distorted/corrupt screen-shot of Audio Engine Options, which revealed that Sibelius either (a) failed to find any connected audio output device, or (b) failed to open the MOTU audio output device.

Thanks for your speedy and reliable replies. Under Available Devices was Track 16 (my MOTU sound card) but it was greyed out. Playback Devices just showed General MIDI (Basic) and nothing else. > Furthermore, when I tried to play a composition that had worked before, it would not play (no sound). > Sibelius Error 40201 Undefined external error (MMSystem/out) > When I came to run Sibelius, I got the error: Due to Microsoft Windows 10 April Update, my desktop computer crashed, and Windows 10 had to be re-installed.
