Prohibited Software! This software may be useless.
As per Amazon.com Policies, only full retail versions of software may be sold through Amazon.com. Additionally, please be aware that OEM, academic, promotional, beta, NFR, back-up, recopied, and freeware & shareware versions of software are prohibited.
I called Steinberg and they said they may no longer register Cubase purchased on Amazon.com since sellers cannot verify academic eligibility and this is against their contractual agreements with sellers.
Shame on Amazon.com for allowing this. Refer to the help pages at Help > Selling at Amazon.com > Policies & Agreements > Community Rules > Selling Software
