Unable to submit Love/Bans

Tracks that I love or ban are added to the list of "unsubmitted tracks and tags". So far so good. But when I submit the list, the rest of the tracks are uploaded succesfully and removed from the list but not the loves and bans. There is no error message but they don't show up in my loved tracks and they are not removed from the list of unsubmitted tracks and tags. I'm using pocket scrobbler on HTC HD2 and have tried both 1.8 and 1.9. Anyone any idea?

I have been scrobbling from pocket scrobbler successfully for over a year now, but just this week, I can scrobble the tracks, but my tags, loves and bans don't get uploaded. The first track that I had this issue on was 坂本龍一 – Field Work (London Mix) (2009 Digital Remaster) (Feat. Thomas Dolby) (4:05). I am scrobbling from a Sprint Samsung Intrepid which runs Windows Mobile 6.5 Professional.
