Have you made mafw-lastfm work?

I have created user settings file (eg. set password and username) and I am trying to play some songs, but they will not appear on last.fm page.

I also tried to start manually mafw-lastfm from command line but it says this:

message failed, trying to send in 5 seconds.
retrying to queue message
message failed, trying to send in 10 seconds.

This will continue and seconds will grow but nothing happens. Any ideas?
