Hi Jim,
Welcome to the forum. As Chris states the d/b with the system is well out of date. We however have a team busy updating as you read and any aircraft not included will be updated as and when clicked on. You may however find that some aircraft existing on your sytem will be incorrect and will require to be amended manually. Ask on the forum when ready and you will be talked through how to do it.
To gain an idea of the updating of the database being done, have a look at the database update thread.
Again some silhouettes of new aircaft which became available in the intervening period will require adding, again ask and these will be forwarded to you.
You may have to download the appropriate drivers if your computer uses Windows 7 or 64bit drivers. These can be downloaded from the support pages. Other than the drivers load it in to your computer plug everything in and it should work away.
Anything else just ask and someone will always be happy to help.
Alan
