Nokia 6230

I have managed to set up a playlist on my phone playing songs from my MMC card (original 32 MB card that came with the phone). Then I deleted one song and added another (through bluetooth).

Now when I click on the playlist folder in audio manager, it freezes. How can I adjust the playlist or create a new one?

Any help would be reatly appreciated b/c this is one of the best features of the phone.

Thanks
