Good morning, it's 6:30 here and I'll have a look at this issue now...
1.2.0.0 if you use the SimShaker shortcut it automatically checks for updates. Future SSA versions might come with additional update checker...
This error says, that you don't have some database entries for the Hornet. Usually the database updates automatically. I'm not sure why it did not on your side. What you could try, make a backup of your settings. You can export/save your settings from SSA BUT please do also an oldschool backup with pen&paper or screenshots!!!!!
After you made the backup, you could reset the internal database, this will remove ALL settings!!! There is a button in the service tab of SSA.
And then, try again...
