I've been using VideoPad over several months and never had this problem before. Trying to make a new video and while I was able to load the video clips just fine and edit them, after coming back to the file to do more edits, something is very wrong with the audio. The visual component is fine, but the audio of all the files is now scrambled. I am able to view the original files in VLC just fine, but when I try putting them into VideoPad, now they're all scrambled again. Not sure what is happening or how to fix it.
