I have just attempted to reinstall my registered edition of FSUIPC4 for use with FSX, using the original activation code provided, FSUIPC4 Key: Xxxxxxxxxxxx and originally purchased on 15 January 2014 via SimMarket under their order no 1098260.Unfortunately, I repeatedly keep getting the error message stating: 'Sorry, this Key is not a valid 12-character Key'I realise that the original registration used my former email address, bob@besinswindon.co.uk but which is now defunct. However, even entering this old address caused reactivation to fail once again.
I have referred to matter to your agents SimMarket but have not been notified of any effective resolution for the issue.
I hope you might be able to help.
