I recently got a Sana E280, which in most respects works very well. However, I'm having a problem sync'ing the playlists between my PC (created in Windows Media Player 11) and it. It must have worked at some point because the playlists got on to the player but now I can't seem to update or even delete the playlists off the Sansa (neither through WMP nor direct on the Sansa). I'm hoping it is just finger trouble, but before I format the player adn start over again (whihc I hope does nto become the usual way to edit playlists!) does anyone have any ideas? Thanks in advance!
