Cubase not recognising my activation.

Cubase isn’t recognizing my license that I bought for Cubase Elements 10 from upgrading from the version that my school gave me. It shows the error message i have attached. I can get onto cubase without any VST instruments but i cannot add them and open them with it working. I don’t have any expired trial licenses on my computer. As the upgrade cost me £42 and i thought that would fix it, i would like to get it working!
