I dont know if this will work for you, but when I bought GS96 a month ago I filled in everything regarding registration during installation and got GS running. Then a message asking me to register kept popping up every time I opened GS. So I cancelled this and GS ran fine. Well, the message got annoying so I called Nemesys and they asked what my CD key number was. I read it to them right off the CD case and they said \"oh thats not YOUR CD key number\" (whatever that means) and they then emailed me a new one. I then registered AGAIN, through that message that was popping up, with this new number and everythings fine now. So you might call or email Nemesys cause apparently they issue you a unique number once theyve got your initial request for registration through the installation process. Thats what I know anyways.
