I bought my daughter an MP3 player for Xmas. I have transferred tracks from CD's and the player plays them OK. I have purchased and downloaded tracks from Woolworths site and they do not play. I have downloaded them to the PC and transferred them and also downloaded some direct to the player but they will not play. However if I connect to the PC and play them via Windows Media player they do work. The player is a Logik 1Mb player, I am running Windows XP and Media player 10.
