i downloaded it but its requesting for registration code

I'm trying the trial version to see if this is the right program for my needs. I need a blue ray with menu creator. My question is, after I created my menu and burned sample videos on a blue ray disk, why doesnt that custom menu show up? When playing back all I get is black screen with play movie and chapters. All the menu and title bars are gone.

I am trying to download the trial version of the Blu-ray creator, but when I try to open the app it says the it is damaged and that it should be removed.

downloaded imelfin for downloading youtube.  Second try to download failed and no files were shown in first dialog box for downloading.  Also plays as recording and I thought that there would be a fast track download speed available?

is the trial version limited to only ten minutes of recording?
