HTC Desire - Spotify doesn't synchronize all my playlists!

[duskwind]

I organized several albums (no local files) in Spotify in folders and playlists. Then I started synchronizing the music to my HTC Desire with both applications running.

At first synchronizing worked fine. Now part of my playlists have been synchronized and some haven't even though there is still enough space on my sd card.

Opening both applications anew does not trigger synchronizing again and when I do that the HTC Desire appears in the devices list at first, but vanishes after a few minutes.

I'd really  like to have all my playlists available for offline playing.
