On the 24.02.2009 I purchased the FS 2004 FSDT Scenery for Geneva. I was sent a serial number (FSDTGVA-PXCP-92GP-Q0WT-MCQ2-YAP9). Because of the changes over the years this serial number does not work any longer. When I was reinstalling my FSDT sceneries I asked and received all the new numbers for my FSDT sceneries except for Geneva.
Please could you check on your system as to what the challenge is. I am happy to provide you with anymore information you require.
Regards
