I just purchased and installed VideoPad Pro v 8.67 yesterday. I've attempted four times to upload my video to YouTube. It's uploads and and the very end it goes to "failed" status. On my YouTube account, it shows the video in my list, but as "processing" and it never moves. My account is long established and verified, so although my video is 18 minutes long, it should not prevent it from uploading. Any advice as to what I can do?
