Contact the help desk and tell them your 2009 is not showing in your time line, presumably you entered the 2009 serial number here

Help desk is a bit confusing so I've short cut the route you need to take, you will need to log in at some point though.
https://support.trainzportal.com/index.php?/Troubleshooter/Step/View/1 click other then Submit a Support Ticket, give it a meaninful title such as TRS2009 missing from my timeline, then state the same in the report, if you have a serial number probably worth sticking that in as well as it's some time since that offer was available.
To the others expressing doubt, the 2009 giveaway has frequently been missed from the time line, happened to an acquaintance of mine a while back, easily sorted by the help desk.
