Playlist Management on n-Streamer/NDX

I own an NDX streamer and I'm using the Ipad App "n-streamer".  I can not, for the life of me, figure out how to manage any aspect of creating, editing, importing (from iTunes) etc. any playlists.  I accidentally added a song to "playlist 1" and now can't figure out how to remove that song, etc. etc.  The user "controls" on playlists seem non-existent.  I have hundreds of hours invested in ripping in CDs on a UnitiServe and now my ability to play various playlists is nil.  I'm afraid to just playing around with lists since I can't figure out how to delete or edit them.  Any ideas out there?  Thanks so much.  John
