New USB adapter arrived and loaded the NDB first time, no problems at all.
Just in case this is the adapter I bought, I'm running Windows 10 latest
version.

Thanks for your advice.

I've ordered a new ftdi chipset usb converter.

Most likely the FTDI converter will work fine (unless its an
unfortunate crap clone). The driver use by software load and
HL32 are slightly different, and we've seen numerous cases
where only one of the two work with some converters/drivers.

Let us know how it goes,
Thanks,

PS: This is why I made the SN10-USB adapter, so you can just
use a memory stick (avoiding endless Winbloze issues)...
