I still am on FS2002 and i recently reformatted. I went to redownload FSUIPC and when i tried starting up SB it came up with this error saying i am using a unregistered copy of FSUIPC. Im like ok no big deal. But when i log into Vatsim i cant see anybody. Its weird though. I went on Servinfo and got a Controlers callsign. Private messaged him, and he responded. But i cant see him on the list of controlers? Any ideas?
