PcCompanion won't open

[Mikey8s]

 Good news, I was able to access my cameras in PC companion. What I had to do was change the video input setting to S video.  This also works in ISpy.

Glade to hear you figured it out.
If I remember correctly you'll need to set this each time you open the camera viewing in PCC after restarting PCC as windows for what ever reason doesn't save the selection for the va12.
