foobar2000 and media control 4.0 - how?

Ok, after installing v1.1, foo2k.dll still showed that it was 1.0.0.0. I used Live Update to grab 1.2, but foo2k.dll still said 1.0.0.0. I uninstalled it using Live Update, and foo2k.dll was gone, but foo_tlbRC.dll was still there, so moved it to a temp directory and ran LU again to install 1.2 again. foo2k.dll still reports 1.0.0.0 and foo_tlbRC.dll was not reinstalled, so I moved it back. Now, not only does MC not see when foobar is running, I can't even start foobar by clicking play anymore, and the MC tooltip only shows the foobar icon (the message it used to display about not finding the player is gone).
Edit:
Ok, I refreshed TLB, and now the tooltip is back saying "Foobar 2000 player / player is not running" and I can start foobar by clicking play again. I tried a full reboot, but I still can't control foobar or see the song info from MC.
