Just got a Canon A520.I loaded the software into Mac OS10 and took some pictures. I downloaded the picutres through "CameraWindow" to "ImageBrowser" and everything was fine that first time a week ago.

I just took some more pix. I plugged the USB into the Mac. Plugged the other end of the cable into the camera, then powered on the camera. I clicked on "Camera Window" and it says "No camera was found".

Please help, what do I do?
