When searching for a valid Multiplayer session never finds game. Details ...I followed 'VATSIM UK Pilot Training BASIC unit 1'. All s/w installs OK etc & have added 80.249.98.88 to ipaddr.tx OK. I can get FS2004 running OK. Then set up Multiplayer OK. HostSB runs fine. Problem occurs with SQBox (v2.3) which does not find the running game at all, just keeps searching. Tried 127.0.0.1 also. If I cancel it runs up OK with some error but appears to work from then. Obviously no connection though.Oddly it worked the 1st time I tried it but not since. Have tried:Disabling virus & Security.Re-installing s/w.Double checking all files in procedure etcNo joy & am very frustrated.Need some diagnostics to see why it can not find session if available.More details available if required.Win XP Home 3Ghz box.RegardsAndy Smith

Read the FS9 setup doc at www.vatsim.net/prc its Vatsim 103d.That will cover the major things to look for. Like router ports and so on.
