OK, so all of my "know it all" kids have grown up and moved out, so I am a little behind in the newest technologies.

Can someone please help me get music from my computer to my mp3 player?

I managed to download from LimeWire and the music I want is on my computer. However, when I try to send the music to my SD/MMC media, I get an error message that says my disk is write protected. How do I fix that?

Thanks in advance to anyone who can help this "empty nester" put some tunes on her phone.
