eLicences lost on my laptop

Today I need to use my laptop, which always had the same Nuendo licenses. It wanted me to download the latest eLicenser software which I did. Then when I put in my USB dongle, it shows NO licenses at all. I’ve had Nuendo since version 2. My latest license number is for an upgrade from 8 to 10 and its not accepted when I enter it.

Nuendo runs on my office PC, but I don’t know how to get Nuendo licensed again on my laptop. Anyone done this? I ran maintainence which seems to have removed the licenses for the laptop. No licenses show up on the laptop, but they are there for the office PC.

My office PC is on Windows 7, and the laptop is Windows 10 if that makes any difference.

They’re back. I’m not sure why. I did get a message I needed to update AVast. Perhaps it was blocking some ports to the internet. But now the licenses show up again, and Nuendo will boot.
