I gave up on this workflow [because I was too lazy to figure out what was up] a while back when I got this error:
Ultimately, I migrated to Rdio for a while. I'm back to Spotify though.
Launching the workflow, I got the error above. I replaced it with the latest version, and I'm still getting the same error. I tried 'Kill update library' and 'Reset Settings for Spotify Mini Player.' What is my next best bet? I would love to get this up and running.
