cam2pc not seeing my Minolta Dimage S304

I have a Minolta Dimage S304 and I use cam2pc (great program!). I used to be able to simply plug the camera into the USB port, turn the knob on the camera to transfer, and it would launch cam2pc and ask to transfer pictures. Now the program doesn't even see the camera. Adobe finds it and it's listed as hardware that's working. Can anyone tell me what I have to do to get cam2pc to see my camera?
