Hi Toon,
this is not the right forum to talk about this issue (not really Nuendo related) but I will try to help you here. First off, make sure you can see you USB-eLicenser on the left handside of your eLicenser Control Center. If you don’t, then the problem is that the key itself is not being picked up by the computer. Just unplug it and put it into a different USB port until you see it in the eLC. If you can see it, but you don’t see any licenses on the right handside of the eLC, try running the Maintenance tasks (button on the upper right corner of the screen) and see what happens.
If neither of those help, you will have to wait for the support to get back to you.
Hope this helps!
All the best,
Luis
