Hi and welcome,
I sent you PM.
Btw to activate the upgrade license, you don’t have to install Cubase LE 5. Just make sure the Soft-eLicenser has been created in your eLCC application. Reactivate your Cubase LE 5 to this Soft-eLicenser. Enter Activation Code of Cubase LE 10 upgrade. Cubase LE 10 license is downloaded to the Soft-eLicenser. Download Cubase LE 10 Full Installer, install it and enjoy.
