Using J3 with Napster/Rhapsody - Playlist do not sync

[Thumper]

Hi,

is anyone of you using the Cowon J3 with Napster/Rhapsody (Napster was bought by the latter but in Europe they kept the brand...)?

Using the new software "Player Sync" which should allows you to sync MTP devices I am not able to transfer any files.

In my case the software correctly detects the player and allows to transfere the license and everything. But if I try to synchronise a playlist it just shows a synchronisation animation for some seconds and then states that the playlist is synchronised. (obviously in this short time nothing has been transferred)
I have a Creative Zen Vision:M which works fine (at least after some troubles) - there the software after some seconds starts to download the files and to transfer them. (This player however is a "MTP-only" device - the only difference I could think of, besides the hardware itself)

I obiously set the J3 into the MTP mode and as it is a new one, I suppose everything else should be set-up correctly, too.

(As this is most probably the next step napster support will propose: What happens if I format the J3? What files should I back up / is there a "reset to delivery state"?)

I hope that anyone of you has already been through this and can help!
Thanks

Hi,

I solved it!
I just am transferring several albums using the player sync.

My solution:
Just delete "Music" and "Playlists" folder and let player sync automatically generate new ones.

... seems to be this easy, at least that is what I did just before it started to work.
