Ok I saw that I was online with my FS 2004 on ServInfo but when I try to get online with AVC then I get the message" Your Callsign was not found, log in on a VATSIM Server before joining a voice channel "But I was already login on a VATSIM Server Europe-C 137.56.244.9 that is the new one.I also see other members online.So why I can't get online with Voice.Thanks

Hate to say this but are you using the same call sign? A little thing but, I have encountered the same problem before only to discover that's all it boiled down to.regardsPaul

Yes I use the same callsign, I hat this problem not when I was using fs2002, but have a nw pc and now I use fs2004.

Got a router?Try changing your sound device in AVC see if that helps

OK everybody thanks for the help but I have mannish the problem, its not UPS1138 but ups1138.Very strange.Thanks everyone.
