Out of the blue my camera stoped uploading pics to my zoom browswer. I have uninstalled and reinstalled zoom browser numerous times to try to fix it. I have tried to reinstall drivers but nothing seems to work. Any ideas. My camera powers up when I connect the USB cord but then when nothing happens. Zoombrowser does not start like it used to on its own and when I start it myself and click on the camera Icon to try to download it tells me there is a communication problem. Any advice or suggestions would be greatly appreciated.
