*F17.gau must have been type-o. 
I asked him for the key, but he said he could give it to me, but needed to do some recoding to make it work (2 days ago.) I wrote back to him asking when that new code would be ready, and haven't heard from him since.  
Eric Manciano: 
"I can give you the key, but it is not usable. I must integrate it in the code of the radar gauge. I will do it soon." 
This is why I thought it had never worked. If he has to change the code, then how can it have worked before? Mabe I just got confused. 
I now wrote to him just now again telling him what you told me, and asked for the F16.gau key. 
Sounded like a pain in the butt, but you shone a light on it for me (and what a light it was!)  
THANKS!
