I have upgrade windows 7 to windows 10. I have a Cubase Le 8 which I got from purchasing focusrite studio. I already activated Cubase le 8 on windows 7 using elicenser but after I upgraded to windows 10 my all apps were uninstalled. so I have to install Cubase le 8 again. after installation when I try to activate again it says "the activation code has already been used. the activation code can be used only once to upgrade or download the license. please contact your software vendor to get a valid activation code" . I got the activation code registering my focusrite hardware. what should I do?
