Wheres Dropbox Setup?

I really want to like this app. With an older version, I was able to connect to DropBox and play FLAC files stored there. I cannot find how to do that in the new version, the developer website is not functioning, and I cant find an app manual anywhere. I bought this for the DropBox connectivity. Without that, Capriccio is essentially useless for me.
