I switched of the Firewall and the antivirus protection, but no succes. Hello together, Yesterday I did a new installation of FSX and FSX 2 skydemon on my desktop and also on my laptop. Good luck everybody and don't give up!!! It's cool to practice on sim having more feelings like it was real world. I wasted a lot of time but it looks like the problem was in op system or it's settings I never have discovered. Than I did it on anther machine, same - changing sys from Win 8 to Win 7 first. Just fresh Win 7, rough (no any addons) FSX steam and fsxtosky demon. Once fsxtoskydemon was installed within seconds got connected and AC position was displayed on IPad!!! Just IPad IP to be properly set. Recently I have decided to try again on the same machine but before it happened I had changed system from Win 8 to Win 7. Tried everything, all kind of settings including FSUIPC and so on. Well it was some time ago I was trying my best too, it took me weeks if not months and finally I gave up.
