Khartoum HSSS vs HSSK

boss
with all respect… xplane are using (navigraph) exclusively as their navigation system service provide…
and I paid for you to use ur service…
and now you are telling me (your customer) that it is xplane problem not yours? and using the word (again) as if am nagging you?
pls solve this technical issues with ur client (xplane) instead of complain it to us (ur customers)!
regards.
