ArrCab recognition problem

I am using "arrcab" in both FS2002 and FS2004 successfully, except when flying a Fairey Gannet. In FS2002 arrcab recognises this aircraft and it takes off using the catapult. However in FS2004 it tells me that the Gannet is a `Tail Dragger` and can`t use it. I`ve checked the air file which is correct so assume its some sort of FS9 niggle.Has anyone had this probelm and solved it or can offer me any advise on How To....Many thanksGeorge
