"no content selected" error on nokia 5310

Question

So i bought a pretty little 5310, and am loving it so far. have hit a few speed bumps when trying to upload with my mac, but have got alomst all of them fixed. almost.
the last time i updated my music library, i noticed my dedicated shortcut keys on the left of the phone no longer work on their own.
when i go through the menu, or use the shortcut key to initially access the music player, the dedicated keys will work for pausing, and skipping tacks. but, say i'm at the 'home' screen of the phone , and just hit the keys on the side. .. they show a 'no content selected' error.
when, in the past, after my first library update, if i hit those keys at ANY time, wether the music player was open or not, it would automatically play my library.
there is probably a ridiculously easy solution to this, but to hell if i can figure it out!
i've read every post on every board i could find, and read the manual six times.
any suggestions?

Answer 1

i've fixed the error!
apparently, the phones have TWO music players.
one in the menu shortcut key, and one buried in the 'media' section on the phone.
apparently, to play a playlist from the dedicated keys on the side, you have to use the BURIED music player in the media section.
once in there, select playlist, and choose your playlist. for me, i had to create a new playlist and manually open AND add EVERY song in my library to that new playlist, so that it would play nonstop with the keys.
try that - it may be the same issue for you, as my problem happened after i reformatted the memory card and re-added new music.
