Hi Dr. Sassi, Thanks a lot for your reply. The downloadlink on Cineversity is now working properly. Please apologize for my overly frustrated tone.
Best wishes

Hallo, Cineversity is part of my employers subscription. The agency I am working for is already registered at Maxon. I am already signed in and still, I am forced to register for a File download in Cineversity. I had to wait for an email with a download link that did not work, Bad Request - Invalid URL. This happened on several occasions. The Registration for every Download is redundant, disruptive and not even working . Please fix this - Thank you.
