CD Rip non-functional under Windows 7?

I saw the question which noted this under XP SP3, and several options were presented for solving it (and the question marked solved). I have tried all of them and they do not work for me. I have two machines running win7 (one is release, one is beta), and Songbird 1.4.0b3, Build 1303 (20091007151242). I erased my profile and the files associated, and checked to be sure the add-on for ripping was installed, but no matter what, I never see any indication that ripping exists. No sidebar, no nothing. Help?!
