Trying to use 3 Cube media player (installed with ultimate droid). I start it, get a message box that says "No music on this playlist" and "Could not find any music for this playlist on your SD card, please reload the application or change the playlist..." -- then an "EXIT" button. It closes, and then I can repeat this all over again. No options for settings, changes, menus, etc. What am I missing??? Also tried updating / installing it from Market. Same message.
