Importing from Beat Builder

I downloaded Java & Beat Builder & added a simple beat which I saved as prompted.
When I try to import it to BBM [File > Import > Song & locate the file on Downloads it won’t let me choose the beat to import. I know I am doing something wrong but for the life of me…
Can you enlighten me?

Regards,

As BeatBuilder saves as a midi file .mid—not .sng) , then what you should do in BBM is to click on the section of the song you want to add it to and navigate to the midi file and select Open.

Thanks. Knew it would be something simple…
