Have a small problem with trying a new callsign in SB. I change to a new callsign in the "Connect" window and get a message from (AVC, I think) that says "Callsign not found. You need to be connected to a VATSIM server to connect" I know there must be something simple I'm not doing, but can't seem to come up with it. Any help, anyone?

That message is from AVC and NOT SquawkBox. So checking the AVC window will show you where you must make the callsign match...

Thanks, Richard. I knew it was probably something simple, as everyone does not use the same callsign always.
