Sorry to hear that she isn't working, Dan.
Your description looks like a protection issue. If you had the demo installed first, make sure to uninstall it. Then (re)install the plane following these steps and really mind the correct code no extra blanks and stuff. http://www.captainsim.org/yabb2/YaBB.pl?num=1322008495/34#34

If it still fails to show all displays, please report back. Your dll.xml may be worth a look then.
