Crashes – M2S for Spotify - Transfer Songs and Playlists Review

It crashed every time I try to add songs . I have iTunes Match . I don't get it. It allows me to see my iTunes music and create a playlist to add music to , then crashes. Also, there is a 5000 song max. Disappointed and want a refund.
