Hello, I am using flightsim 2002 and I have the FSUIPC 3.03 installed. I am told that I can´t be seen on Vatsim because I have not registered an application. Every time I get in to "Modules" "FSUIPC" and type in squawkbox.exe and the key, it says thank you and restart program. I do this but it seems that when I start it again I´m stuck with the same problem...I does not save the typed in application or key. I don´t know if I explained my problem well enough but if anyone has any ideas of what to do, I´ll be glad to try. I´m not very good with computers so please keep the language understandible for us "mortals" =). Greetings Gabriel
