Hello Umberto,
I am copy/pasting the serial number from the receipt that I downloaded from my account as a .pdf from Digital River. I am not typing the serial numbers into the registration box. My serial numbers are not working for these three airports only, every time I try to activate them.
I have all of your airports and the others work fine, so my chances of repeatedly making the same mistake as I copy/paste the serial numbers on these three particular airports would be very small.
Please check these three serial numbers for me, to be sure they are active.
The complete message says: "eSellerate ERROR - 25001 Serial Number not found, you probably just placed the order please wait at least 15 minutes to update servers."
The most recent of these three purchases was done about a year ago, so waiting 15 minutes will not accomplish anything.
What can I do to get these airports that I purchased from you working?
If you have to, give me credit on these three airports so I can repurchase them and get new serial numbers that work.
In all the years I have been buying payware addon products for MSFS, I have never ran across anything like this.
Thank you,
Bob
