hello,
I'm somewhat new to computers and I use limewire. I had not had any problems like this till today. I use windows media player. When I double click on a downloaded song it would go straight to windows media player, also the icon next to the songs in the search had a WMP icon next to them. Today when I did my search all the icons came up as iTunes, and when I double clicked on the downloaded songs it whent straight to iTunes. I dont like to use iTunes and want to put it back on my WMP. Can someone explain how I do this? thank yo Lizzie
