I did what you said Mike,
First install any patches that Frodo may have from here:Patch Thread !
1) Look in your Device Manager for "USB Serial Port (COMX)". The X is the port number your XM Radio is using.
3) Then look in FP Settings1 under XM Radio. Put the COM port from above into this Com Port: box.
4) If this doesn't correct the problem, look in FP Settings2 under FrodoCam. Uncheck the FrodoCam Trigger Enabled checkbox. Also set the ComPort: to some value other than the value you put into the XM Radio settings window.
