I have been looking for a key/keygen (yes I know, shame on me) for FSNav but have failed in doing so. So, I am wondering if any know any good Navs for FS9? Or does anyone know if FScommander is any good for it's outrageous price?
Or is anyone willing to cough up that key for lil' ol' me? 
I doubt it...
After forking out 35 Euros for my official version of FS Navigator and the Key, many years ago, I keep my Installation Program saved on my CD, and my Registration Key locked up in my Safety Deposit Box!
Each Key is peculiar to each official downloaded Program, and I doubt if they can be exchanged.

P.S. FS Nav was never released for FSX...which is the
main reason why I don't use my FSX Sim!...

...!
There is an (poor) alternative to FS Nav....do a search...
