I don't really know what I'm doing. I don't know where or how to start squawkbox, or in what order with SBRelay. When in flight simulator, I click on "run" in the SB host menu and a grey screen pops up with the title "SB Host," but thats it. It is just a grey screen. I have read that people say to use the SBHost.exe that comes with Squawkbox, but I don't see that application in the Squawkbox file that I downloaded. I'm confused. I've read the tutorials in the Pilot Resource Center and they helped a little but the SB Host still doesn't run. I would appreciate any advice that any of yall could give me. W.
