The 404 error is related to Spotify-owned playlists (and should be gone in the version released last week). As your playlist is user-created, these logged errors can be ignored.

The problem of "0 out of 0" seems to be the same issue as reported in #65. Sadly I have not been able to reproduce this yet. If you want a workaround, you can delete the database created by the plugin (plugin.db). The next import run might take a bit longer but it helped in #65.

Did you encounter this problem after it already worked once? So did you at some point have successfully mapped tracks in that playlist or was it showing "0 out of 0" since the first import?

Also, what settings do you use for that playlist? -> So, is Always from scratch enabled or was it imported as part of a "full user" import
