Steinberg Eucon Adaptor

My Steinberg Eucon Adaptor is suddenly today not being recognised in Cubase 9.30. It was working fine yesterday. I have uninstalled and re-installed version 6.5 64 bit but it will not show up in devices. It is not in the list when I click the add button. It is being recognised still in Cubase 8.5.
Any ideas please?

You don’t need to install a seperate eucon adaper, just install the latest eucontrol and the adaper included in Cubase

Thanks. I have done a Cubase repair and it is working okay now.
