Importing/Exporting to sd card

I haven’t added anything new to BB Manager in quite some time and am now having difficulty, very confused. I believe I have updated firmware and the updated Manager but is their an updated manual on how to create a song or project and import/export and then get it to my SD card? I guess I need a step by step guide that is current. Or would you suggest uninstalling and reinstalling? Any guidance would be greatly appreciated.
Thank you.
