Yet again, one of my files is not going to show in Media Viewer or thumbnails. The direct file works, though. I was previously told that it might be the thumbnails and pngs still generating, and my other files' problems solved themselves after a few minutes or hours, but this file has had problems since it was uploaded 2 days ago.
