I don’t know what’s up... – Add Music to Video, Maker Review

It doesn’t work when I post music with my video. I always try to play the video and it doesn’t even play, the video ends up freezing. I don’t know why this is happening. It also freezes when the video is saving... this is so frustrating! I spent all this time on a video for no reason.
