Course manager iTunesU error

I created an iTunesU account in the Course Manager as an independent instructor (my college does not have an iTunesU account). I can log in to course manager but the only thing I can see is the Instructor Info page, my institution has been cleared, and I'm asked to accept the terms and conditions again. I fill in everything and agree to the terms and conditions and I get the the message: "'Course Manager had an Error' click to reload." When I click to reload it I'm taken back to the instructor info page and what I had just entered is gone

I was trying to create a profile using another Apple ID with @icloud.com or @liceorespighi.it , but it is the same situation!!!!!

Someone could help me. Thanks
