Musicbox not scrobbling to Last.FM

I recently installed Musicbox because it had Last.Fm support, and well. It’s not working. When i play a song on it, it shows up on my Last.Fm page like this. But it doesn’t stay once the song is over, aka, doesn’t scrobble.

Anybody who can help me fix this?

Where are you playing the songs from? Spotify? Gmusic? Local? What version
are you using?

Using 0.5.4, and playing from GMusic.

This is probably the same issue:
