Hi, I am new to this and tried to design a mission. So far, as a single player mission it worked quite well. The problems came up, when i made a multiplayer mission out of it. I followed your description above. Wheni started FSX again and logged in to gamespy i wanted to host a session.The following error message came up:invalid argument detected (or something like this. I got that message in german, so please excuse a possible bad translation)I am able to host a session than, but unfortunately no free flight session anymore. Just missions.Does anybody know, how i can get that possibility back without re-installing fsx?Thank you in advance for your helpJ.B.Wings
