I did have one somewhere... I since moved house and would have to dig around to locate it. Although you do realise that it will only work for version 10 and below? Versions 11 and 12 only use UN and PW activation over internet. I'm 99% sure this is the case.
I use v11 and v12 and can't use the dongle which is why it is buried somewhere amongst my things.
Let me know if you are still interested and I'll have a decent look.
