Here's the a video from my Nikon D7100. As stated in the post I can't move to Edit & Trim, audio plays from import panel, no video, after conversion no audio only video. I do have a HP Envy but all worked fine a few days ago. Also now I can't move GoPro files to Edit & Trim panel. I am working with a GoPro tec but have tried his recommendations without success. Sorry it took so long to get this to you but I don't know Dropbox and am new to forums. My computer skills are lacking. Thank for your help. Here's the link to my Dropbox file. Hope it works.
