Problem Importing GoPro 2.7k Media - Imported as Audio

I have a video project of almost two hours that I can't even get imported into the media of Hitfilm. I tried new settings on my GoPro and wanted to compare some footage. Unfortunately, I can't do anything with it in the editing program, as it only imports as an audio file. It is the audio of the video, but it's useless. I don't think it's a problem with my computer, as the raw footage plays just fine outside of the GoPro program I have installed; it plays from its file location on a different program. 

Please help!
