When you posted your question on the VATSIM forums, you posted it in the best place possible, and you have already been helped there. Do not run SB from within FSX, run it externally as strongly suggested in the Tips and Tricks thread in the SB Help thread on the VATSIM forums. Also, just to be sure, you do know that you should not be attempting to run the same version of SB on FSX as you did for FS9, correct? Suggest you follow the Tips and Tricks thread, and continue your request for assistance thread on VATSIM forums.
