login page messed up, can't log in

When I launch SL now I get an odd login screen. The picture is something I've never seen before--a wireframe overlayed on the terrain. There's no status messages, concurrency count, etc. And the menu bar is red, as if I'm running a custom client, but I'm not. I'm running the 1.20 release client. And, it won't accept my password.

I've re-installed, cleared cache, etc. Still no go.

Any clues?

Nevermind. It was trying to log me in to the wrong grid.
