I have same issue as Locarno1 described, also on FSX:SE... I think Im going to uninstall this scenery and I will go back to one from www.vacc-cz.org which is not perfect but it is flyable. I hope that aerosoft will fix this issue quickly.
Recently we have seen a lot of codes used to unlock our products being offered for discounted prices. Almost all of them are bought using stolen credit cards. These codes will all be blocked by our systems and you will have to try to get your money back from the seller, we are unable to assist in these matters. Do be very careful when you see a deal that is almost too good to be true, it probably is too good to be true.
