I have a registered Pete Dowson's FSUIPC. I was using it with Windows 7 but now installed Windows 10. It now says that it is unregistered. I don't know my key code. Am I out of luck and have to pay another $30 or is there some way to get my key?
Thanks
Carl

He will probably want the email name that you used to prove that you bought it.
