Topic: Can't submit to FilmFights

Hi everyone, I made a Haiku for the next Fight, uploaded it on YouTube, and tryed to upload it on the Fight.
I put the Thumbnail (640, 360), and tryed to put the video (1920, 1080) in the form to submit.
When I press the "Ok, Upload my video" button it upload the Thumb normally, but the "Submitcheck" page stay this way:

And I already tried the link of the video, the embed code (<iframe>) and the embed link (yt.com/embed/(video))
