The Rip Music tab in the Options window is where you customize the ripping options, not where you actually rip from. Launch WMP and, if using v10 or v11, click the Rip button along the top. If ripping doesn't begin immediately you can check the boxes for all songs you wish to rip and click the button along the bottom. Note that from the Options->Rip Music window you can customize what format they're ripped to (recommend MP3 for compatibility with other apps/music players).

Hope this helps,
