Vatsim not connecting

When trying to connect to VASTIM with vPilot 3.9.0 I keep getting the error , “Command failed. Please ensure that a flight is loaded.” I have a flight IS loaded prefiled on VATSIM. YES (I RECENTLY DELETED THE VPILOT AND INSTALLED AGAIN)

That error usually occurs when you try to connect while you aren’t sitting in your plane in the sim (i.e. are still in the menu). Load an aircraft first (so that you’re actually sit in it in the sim), then connect.
