Firstly I want to apologise for my rant yesterday; I guess I was just venting my frustration and anger, and I'm sorry.

However, in the cold light of morning, and with a relatively clear head, I read through the posts and something blatently obvious jumped out at me.
The laptop with BB2020 (working OK) is Windows 7 and the laptop with BB2021 is Windows 10.
Doh!
I've had the Edirol UM1X for a long time - probably since XP days - and what you said about updating the drivers makes perfect sense.

I'll poke around and see if I can find driver updates.

Thanks for your help and for your encouragement to keep trying.

Cheers,
Keith
