Hello.
Read this:
https://mediawiki.ivao.aero/index.php?title=IvAp_manual
On IVAP configuration uncheck "autojoin(FS2004 only)"
Start FS9
FS menu : start IVAP user interface
wait some seconds and don't connect Ivap
FS menu:
flights
multiplayer
connect
Join IVAP
You get message:
"IVAP has joined the session"
Then with IVAP user interface you can "connect" with
callsign; account: VID and password...
Don't forget to start at parking and to send a flightplan !
Hope this help
