Hello Nigel,
Excellent -- glad the Windows 10 PC issue is now solved too.

When the PC is re-booted all works again. Could this be a firmware/driver problem in which case an update may solve it! My difficulty will be updating the Windows 7 OS without internet access in the church. It seems that others may have had similar problems.
I can only guess, but I would think that it's quite likely that fully updating everything (Windows, all drivers, all firmware, PC BIOS, etc.), then reinstalling the MOTU driver could fix it. I would definitely advise doing that as a matter of course anyway whenever using any new hardware or software on an existing system, since current drivers and firmware will almost certainly have developed for and with current versions of everything else.
Best regards, Martin.
