Traffic Does Not Show in the Air

[Deltaguy 45]

Using P3dv5 and all the traffic is great on the ground around the airport, but the minute the plane departs the runway it disappears.  Same happens when an aircraft lands, it suddenly appears out of nowhere down the runway.  Is there a setting missing somewhere?  All seems to be perfect on the ground.  I can't get a single aircraft to show up in the air.  I have waited 30 minutes and tried several airports.

Tried all of that, still no luck.  I can follow an aircraft on take off, but as soon as it lifts off, it disappears.  No flights in the air at all.

Re-install RealTraffic. Make sure you have set FlightSim in use at PSXT.
