Ok, update, I've been trying this using my main system, Windows 7 64bit, this system has had all kinds of things attached to it including a Samsung phone via a USB cable. So, I have now tried on my older windows XP laptop (had to dust it off a bit first).
I now have a working Android Market renamed Play Store on my Vox.
So a big thank you to everyone here for all your hard work in trying to Market onto the Vox.
What it could have been is some sort of conflict between the Samsung and Android drivers in device manager it would show up as NTativrv01, but on the XP it showed up as K080.
