You have to go to your settings on Windows Media PLayer and turn off Copy Protection. What version of WMP are you running? I've got version 9, and so I'd go to Tools -> Options -> Copy Music and then uncheck the "Copy Protect Music" check box.

Here's the link to dbPowerAmp, btw:

Hey, I just read the page, and the above link is to a ripper, too. So you can rip directly to mp3. (I needed a converter since I had already ripped all my CDs to wma).
