Odd issue. Sygic 15j on Windows 8

My 3rd party GPSInfo application detects my GPS receiver on COM3, 4800 Baud and acquires a signal.

I close the GPSInfo application to free up the COM port and make it available to Sygic.

I open Sygic, it doesn't auto-detect the GPS receiver. I set the COM port and baud rate manually.

It appears to open the COM port, but says there's no signal and won't display any satellite information.

On one occasion I got it to detect and display satellite information, but I can't anymore. Any tips? Thanks.
