Its okay if you're sharing as a "group" (aka a band-esque situation), so you'd be in a partnership for use (normally installation is allowed for X amount of computers, some games restrict to just 3 computer installations, it varies per instance... Others 1 and some as many as you want... Never tested Vocaloid but I know it works on at least 2 installations). Its a grey area, though your girlfriend would be held responsible for your misuse. ITs only a problem when the user abuses this.

As others have said, you either have to go to Zero-G or in another case, VO forums.
