Im am using the Gembird video grabber. I succesfully edit a film from a VHS Super 8 camera. The next day I tried another video, with the same camera. No sound anymore. I played this cassette on a TV and there is defenitively sound on it. I contacted the helpdesk of Gembird and they recommended me to use NCH software if OBS was not working. I removed OBS from my computer via "settings -apps removing". Now I receive the fault indicating in NCH that my videograbber is in use in another application. So I removed NCH and reinstalled OBS. But allthough it is newly installed, the program is not starting with new settings, but is taking the settings from the time I removed it from my computer. How can I get started again with "blanco" or virgin settings?
