Today, I have tried to upload a video, but when it uploads, it shows a black box, but sound plays.

I have an account, I have unchecked the accelerator thing, I have cleared my cache, but I can't get the picture to show on my new video I am trying to upload. And I don't know what to do, I am losing my god damn mind. Please help me, or find another way to upload videos to YouTube instead of Movie Maker.

If there is any other programs that allow it, please help me. Thank you.
