Thank you for a speedy response however, I'm no further forward
I have copied and pasted all of the details from the eMail and also from the "your order" page on Simmarket and I'm getting the same message every time:
Sorry, this key is not valid for FSUIPC registration
I replaced the name and eMail address with rubbish but kept the same code and got the same message
I then tried replacing the code with rubbish and kept the name and eMail address correct (as pasted from the Simmarket page) and still got the same message
I presumed you would not want the code on public display and if it can help you, my name is Ian McFarlane - spelt just like that in the Simmarket order
I do not see any way I can communicate this with you in private, so I await your advice
