I see… working from home too, we’re all on the same boat.
I don’t have access to the user accounts and the licensing server nor the shop, so I cannot help much here, sorry.
From what I saw in the pics you have posted, you either have a malfunctioning dongle or a wrong license upgrade/update type.
(if the dongle still works with C4, then it’s likely the second).
If you didn’t use a trial already, I’d strongly recommend to request one, so you can keep on using Cubase for 30 days from the activation.
This would also test the functionality of your dongle and give you a time margin to get a reply.
If you have problems with this, please send me a PM.
