Hi, I've successfully uploaded 4 videos, but my fifth one just won't upload successfully. It starts out fine, but when it reaches the 100%, the video just disappears. I've tried re-uploading several times, closing the computer and restarting, but still it won't upload this video. I don't understand why. I still have lots of space left, and the video is smaller than my other successfully uploaded videos, so it cannot be a problem with the file size either. I'm not sure what else to do now. Please help. There must be a glitch.
