League of Legends Community - Multiple random errors after logging in

Hi

Here's what happens: I key in username and password, and enter. Then it's either one of two scenarios

A) One Unknown Error message immediately after pressing enter. PVP.net Client displays "Session Closed. Your session has closed. The application will now exit. Please login again to continue." Internet Explorer pop-up saying "The launcher has experienced an error. Please restart this application."

timeToLive = 0

B) Three Unknown Error messages several moments after the 'doors open', as it were. PVP.net Client is blank.

So when I try to log in, that's what happens. Let me provide the game log and the dxdiag.

I was just invited yesterday. I got the latest installer. I'm aware that there's a scheduled maintenance today. But I have been trying to log on since yesterday, and it doesn't work. I am completely at a loss.
