Files not uploading to iTunes U

Hi everyone,

When I attempt to upload and manage files for my iTunes U course via the browser that launches from in the iTunes application my files keep failing to upload. I have also tried the upload from 3 different browsers (IE, Chrome, and Firefox) but had no luck with any of them.

The video file I made to upload is a MPEG-4 movie and is under 15kb in size, I tried to test this with a small MP3 file as well but both would repeatedly fail.

Has anyone else been experiencing this problem or have any thoughts as to what is going on?

Thank you for the help!
