GPSout and MS Streets and Trips

I was using GPSout with FS2002 and MS Streets & Trips and all of a sudden Streets and Trips says it's not getting any signal from the GPS receiver. (FS2002)To get it to work to begin with I puchased a PCI card with 2 serial ports which I think became ports 5 and 6. I connected them with a null modem cable and changed the statement in the GPSout.ini file from Port=Com2 (the default) to Port=Com5, and I set Streets and Trips to receive on Com6 and it was working fine.I set the speed in GPSout.ini to 4800.Does anyone know what is wrong causing Streets and trips not to receive a signal?Stationair
