Trailer issues and Release date

Hi, 

I am trying to add trailer to my film page that was recenlty released. I added it as a trailer link in edit options twice now and it doesn't show up. 

I also made an account for Scoreboard page but each time I login its 404 error. 

I am also trying to change release date but each time I request that change it never shows up. Any reason? 

I would appriciate the help, thank you
