This one started to work (strange if you did not change other things than logging). Anyway, this is what I did: -Uninstalled QSpot -deleted cache and settings folders -power off from the phone -power back on -installed QSpot -launched with active internet connection -marked one playlist syncable in offline mode -quit QSpot (from upper right, not log out button) -ended internet connection -launched QSpot again -> works Big thanks for your help (and of course for this awesome application!)!
